DETAILED DESCRIPTION OF THE INVENTION
(32) Base Mapping Technique & System
(33)
(34) The image projection system 100 can be used to project all kinds of imagery content, including, without limitation, still photographs, video clips, still digital images, streaming digital video, movies, or any other visual content. Preferably, video clips that have no camera movement (which lends itself to the illusion), ambient images (basically a moving photograph), “loopable” clips (in point and out point matched), and “floaters” (clips shot in front of a black backdrop) are used.
(35) In utilizing the image projection system 100, imagery content can be projected onto different surfaces of the architecture as a plurality of separate images or as a coordinated single image. Moreover, if desired, the image projection system 100 can be modified to simultaneously generate audio that corresponds to the imagery content being displayed. Depending on the nature of the imagery content being displayed, the addition of audio can enhance an observer's sensory experience and/or make the projected illusion more believable. This can be done by adding a separated stereo system, by coupling speakers to the laptop computer 10, or by activating speakers built into the laptop computer 10.
(36) The image projection system 100 comprises a laptop computer 10, an analog/digital (“A/D”) converter 10, and a video projector 30. While a laptop computer 10 is illustrated, any other type of computer or processing unit can be used that is capable of performing the functions described throughout this application. The exact processing capabilities, memory needs, and hardware requirements of the laptop computer will be dictated on a case-by-case basis, taking into consideration such factors as the complexity of the architecture being mapped and the complexity of the imagery content to be projected.
(37) The laptop computer 10 is operably connected to the A/D converter 20 via a connector cable 11, such as a firewire, a DSL cable, a fiberoptic line, an s-video cable, or the like. Preferably, a high speed data transmission line is used. Utilizing a high speed port, such as a firewire port, makes it possible to transmit data to the projector 30 from the laptop computer 10, and project the corresponding imagery onto the architecture in real time.
(38) The A/D converter 20 is in turn operably connected to the projector via a connector cable 21, such as an s-video cable or the like. The invention is not, however, limited to any specific type of connection cable so long as the components of the system 100 can operably communicate with one another and/or transmit data therebetween. In an alternative embodiment, any and/or all operable connections can be wireless, utilizing radio frequency (“RF”) signals, infra-red (“IR”) signals, or the like.
(39) Moreover, while an A/D converter 20 is used to facilitate data transmission/communication between the laptop computer 10 and the video projector 30, any digital video (“DV”) device may be used. For example, in some embodiments of the invention, it may be preferable to use a mini-DV digital camera in place of the A/D converter 20 because the mini-DV digital camera can act as a real time converter. In other words, the mini-DV digital camera can create an accurate registration of the video mapping, and implementation thereof, such that the camera keeps the video aspect ratio and alignment proper and calibrated. While utilizing a DV device that allows real time conversion of data transmitted to the video projector 30 from the laptop computer 10 is preferred, the invention is not so limited.
(40) The laptop computer 10 has a video compositing software application or a similar program loaded thereon. One example of a video compositing application suitable for use with the present invention is Adobe® After Effects® The video compositing application allows a user to see in real-time to a video source. When the image projection system 100 is functioning, the video compositing application allows a user to essentially see on the display screen 12 of the laptop computer 10 (and control in real time) what is being projected onto the surfaces of the architecture 50 itself. This is exemplified in
(41) The image projection system 100 enables a user to utilize a single projector 30 to cast imagery content on multiple surfaces of the three-dimensional architecture 50, such as the surfaces 51-53. The image projection system 100 compensates for distortions when projecting onto the non-coplanar and/or non-adjacent surfaces within the three-dimensional architecture 50, integrating architecture, light, and darkness into an immersive environment.

(44) The user then identifies a location 31 at the work site from which a line-of-sight exists to at least one of the surfaces 51, 52, completing step 915 of
(45) Once a location 31 is identified from which a line-of-sight exists to the desired surfaces 51, 52, the video projector 30 is secured at the location 31. The video projector 30 is secured at the location 31 in a fixed orientation that affords the video projector 30 the ability to project imagery content onto the surfaces 51, 52, thereby completing step 920 of
(46) In traditional prior art projections systems, the video projection/presentation is utilized after all the video is produced. However, with the present invention, the video projector 31 is preferably “locked-down” in place before the video production begins. As discussed below, it is through the “locked-down” position that the mapping process occurs. The video projector 30 can be secured at the location 31 via any means possible, including bolting, brackets, clamping, screwing, nailing, gluing, magnetism, etc. Moreover; the video projector 30 can be secured so as to be easily removable from the location 31 or it can be fixedly attached thereto.
(47) Once the projector device is “locked-down,” the projector device 30 is operably connected to the laptop computer 10 as described above, thereby completing step 925 of
(48) Referring now to
(49) Once the Adobe® After Effects® application 15 is opened, the user opens a composition window 16. Because the laptop computer 10 is operably coupled to the video projector 30, activating a “line video preview” command will project the contents of the composition window 16 onto the architecture 50 in real time (as shown in
(50) The white rectangular area 18 covers the rectangular surface 51, the circular surface 52, and a portion of the flat surface 53. The surfaces (or portions thereof) of the architecture 50 that are not being projected onto are shaded gray throughout this application. If desired, and if necessary, to capture all of the desired surfaces of the architecture 50, the size of the white rectangular area 18 can be increased by increasing the distance between the architecture 50 and the video projector 30.

(52) Referring now to
(53) As shown in

(56) Because the projection angle of the projection device 30 is not normal to the non-coplanar and non-adjacent display surfaces 51, 52, the projection of the imagery content on the display surfaces 51, 52 experiences substantial optical distortion (visible in
(57) The optical distortion of the projected imagery content on the display surfaces 51, 52 can be detected by visual inspection. For example, it can be seen that the stripes projected onto the rectangular surface 51 are not of equal width and are not spaced apart equally. Similarly, the stripes projected onto the circular surface 52 are not equally spaces and are diverging. This “skewing” is the result of the display surfaces 51, 52 being angled with respect to the video projection line. In some instances, the optical distortion of the projected imagery content may be visually detected by viewing the architecture 50 as a whole, and evaluating the continuity of the projected imagery content as it appears on the various surfaces 51-53 of the architecture 50.
(58) Referring now to
(59) As the user adjust the internal properties of the mattes 22, 23, he/she visually observes the effect that such adjustments have on the resulting projection of the imagery content on the display surfaces 51, 52. The user continues to adjust the properties of the mattes 22, 23 until the optical distortion of the projected imagery content on the display surfaces 51, 52 is minimized and/or eliminated. As can be seen by comparing
(60) This completes the mapping procedure. The general layout of the composition window 16 (i.e. the map), including the matte coordinates and the internal properties of each matte can then be saved for future use. The user can then utilize the saved map in the future to insert any piece of imagery content and/or change the imagery content as desired. As a result, the user can easily change the imagery content to be projected onto the architecture 50 without having to go through the mapping procedure by simply inserting new imagery content into the mattes. The internal matte properties will automatically be applied to the new imagery content.
(61) Once the map and desired imagery content is inserted into the mattes 22, 23, a loop is designed and rendered within the video compositing application to effectuate continuous play of the imagery content. The content of the composition window 16, including the looped imagery content, is compressed, e.g., in a mpeg-2 format, and then burned onto a DVD, thereby completing step 950 of

(63) As yet another illustration of an embodiment of the present invention, a user is capable of incorporating the previous application of the masking process into the metal surfaces or cells (i.e., discernible portions of walls, ceiling, floors and general surfaces). Where masking, or use of black, is the major effect needed, e.g., the user does not want to project on the mirrors or elements other than specific surfaces such as metal surfaces, white surfaces, etc. A user would then utilize a video compositing application or a similar program to create video maps that were black and white, black where there is to be no imagery and white where there is to be video and imagery.
(64) Unlike conventional video projection devices that employ “keystone” distortion correction techniques, “lens-shifting” techniques, or similar distortion correcting techniques, the present invention can compensate for multiple instances of distortion on multiple non-coplanar and non-contiguous surfaces within a three-dimensional area. In addition, the present invention can create a masking effect, which creates the illusion of blackness on surfaces upon which the user does not want to project video and images or on areas with no surfaces to project upon.
(65) Projection Kit and Content Projection Method

(67) Referring to
(68) The projector mounting mechanism 210 is provided to facilitate mounting of the projector apparatus 220 to a desired surface and/or structure at a user's site, such as an apartment, home, condominium, outdoor area, etc. The mounting mechanism 210 generally comprises four members 212 and a plate 211 to which the projector apparatus 220 can be fastened, for example by bolts, screws, clamps, adhesives, hook-and-loop tape, double-sided tape, slide-fit assemblies, snap-fit assemblies, etc. The members 212 comprise holes near their bottoms to facilitate rigid connection to the desired surface and/or structure at the user's site via screws, bolts or other fasteners. Of course, the members 212 could incorporate other connection mechanisms, such as flanges, clamps, adhesives, hook-and-loop tape, double-sided tape, slide-fit assemblies, snap-fit assemblies, etc. If desired, the member 212 could be merely adapted to rest atop a surface
(69) The plate 211 is pivotally mounted to the members 212 so that the projector apparatus 220 can be swiveled to the desired orientation even when the member 212 are rigidly secured in place. The projector mounting mechanism 210 also preferably comprises a locking mechanism 213 (generically illustrated). The locking mechanism 213 can be activated to secure the projector apparatus 220 in a fixed orientation so as to prohibit unwanted movement once the projector apparatus 220 is properly oriented and mounted by the mounting mechanism 210. The locking mechanism 213 can take on a wide variety of structural arrangements, including interlocking flanges, a slide-bar assembly, tangs, compression assemblies, frictional engagement, etc.
(70) While the mounting mechanism 210 is illustrated as a separate structure than the projector apparatus 220, it is to be understood that the components could be combined so that the mounting mechanism 210 and the projector apparatus 220 are an integral or fastened together component.
(71) Moreover, the projector mounting mechanism 210 is illustrated as being a “quadpod” style structure for, merely exemplary purposes. It is to be understood that the mounting mechanism 210 can take on a wide variety of structural arrangements. For example, the mounting mechanism 210 could be merely a flange or any other combination of beams and/or plates.
(72) The projector apparatus 220 is a device that has both image projection and image capture capabilities, both of which are facilitated from the same point of view, which in this case is through lens 221. The projector apparatus 220 comprises a housing 222, a lens 221, and a communication port 223 for receiving and/or sending data signals. The structure and operation of the projector apparatus 220 will be discussed in greater detail below with respect to
(73) The control unit 230 is a preferably stand-alone component that acts as the head unit for the image projection kit 200. Of course, as shown in
(74) The control unit 230 preferably supports the following functionality: (i) wireless/tethered video signal connectivity to the projector apparatus 220; (ii) wireless/tethered serial control of the projector apparatus 220 (e.g., On/off, diagnostics, etc.); (iii) wireless/tethered online/network capabilities; (iv) memory expansion; (iv) enhanced video processing capabilities (i.e., the control unit 230 preferably does all the “heavy lifting” when it comes to processing and compiling the video compositions); (v) built in custom software for mapping and playback; and (vi) control over built in image capture sub-system of the projector apparatus 220.
(75) The necessary cables 240 are also included with the image projection kit 200. The cables 240 can include the power cables and data communication cables necessary to connect the components of the system 200. Examples of such cables include without limitation, firewires, USB cables, mini-USB cables, HDMI cables, fiber-optic cables, etc. Of course, if desired, all data communication can be achieved through wireless means such as RF, IR, etc.
(76) Finally, the image projection kit 200 comprises a software package 250. The software package is a video compositing software application. One example of a video compositing application suitable for use with the present invention is Adobe® and After Effects® Most preferably, a customized software package is used that can achieve the functions and render the interfaces described throughout the present patent application. The software package 250 can be included in the kit 200 on a computer readable medium, such as a flash drive, CD-ROM, or other external memory source. In another embodiment, the software package 250 can be included in the kit 200 as an alphanumeric, numeric, alphabetic or other code that allows users to access and download the software onto their computers from a wide area network (“WAN”), such as the Internet, Of course, other purchase verification means can be used. In some embodiments, the software package 250 may even be supplied free of charge to users to promote the kit 200.
(77) Referring now to
(78) The projector sub-system 225 comprises all of the circuitry and mechanical components necessary to project imagery content, such as videos or still content, onto the desired real-world architecture of a user's site, such as a wall, post, ceiling or floors. A detailed explanation of the projector sub-system 225 is not necessary as projectors systems are well known in the art. Similarly, the image sensor sub-system 226 comprises all of the circuitry and mechanical components necessary to sense and transmit a real-world image perceived by the lens 221 as data for recreation on a display device 305 of the computer 300. A detailed explanation of the image sensor sub-system 226 is not necessary as such systems are well known in the art and are commonly used in digital cameras. It should also be appreciated that in some embodiments of the invention, portions of the image sensor sub-system 226 and the projector sub-system 225 can be combined to minimize circuitry and size of the overall device.
(79) The projector apparatus 220 can switch between an image projection mode and an image capture mode by manipulation of the pivotable mirror 227. When in the image capture mode, the image sensor sub-system 226 is active and the projector sub-system 225 is inactive. On the other hand, when in the projection mode, the image sensor sub-system 226 is inactive and the projector sub-system 225 is active.
(80) More specifically, when the CPU 224 receives an image sensor activation signal from the control unit 230 (or computer 300) via the data port 223, the CPU 224 rotates the mirror 227 (if necessary) so that it is at the illustrated 45 degree angle. As a result, the image sensor sub-system 226 is in operable optical alignment with the lens 221 and can thereby perceive the real world image seen by the lens 221. At this time, the projector sub-system 225 is blocked by the back surface of the mirror 227 and is preferably turned off. However, when the CPU 224 receives a projection activation signal from the control unit 230 (or computer 300) via the data port 223, the CPU 224 rotates the mirror 227 (if necessary) 45 degrees downward so that the mirror 227 does not obstruct the line of sight from the lens 221 to the projector sub-system 225. Thus, the projector sub-system 225 is in operable optical alignment with and can project imagery through the lens 221. At this time, the image sensor sub-system 226 is blocked by the mirror 227 and is preferably turned off. Through the use of the aforementioned single-reflex lens assembly, the projector apparatus 220 can both capture an image of the desired architecture on the computer for mapping and later project images onto this architecture from the same point of view.
(81) The control unit 230 comprises a processor 234 (“CPU”), a transceiver 232, an internal memory 235, an interface port 236, and a data port 233. All of these components are in operable and communicable cooperation with one another inside of the housing 231. The control unit 230 communicates with the projector apparatus 220 via the transceiver 232 and with the user's computer 300 via the data port 233. Of course, a single or multiple wired or wireless ports can be used for all data communication between the projector apparatus 220, the control unit 230 and/or the computer 300. Any kind of data communication port can be used, including HDMI, IR, RF, USB, mini-USB, firewire, etc.
(82) The CPU 234 is a properly programmed processor capable of performing the necessary functions described herein and above as functions (i)-(vi). The interface port 236 operably receives an external memory device 260, which can be used to store the mapping and imagery content information created by the user on the computer 300 using the software 250. This data is retrieved from the external memory device 260, processed by the CPU 234 and transmitted to the projector apparatus 220 for appropriate handling. Alternatively (or in addition), the control unit 230 can have an internal memory 235 for storing mapping and imagery content information created by the user on the computer 300 using the software 250. In this embodiment, the computer 300 can transfer this data to the control unit 230 for storage on the internal memory 235 via communication between the respective ports 233 and 303.
(83) The software 250 is loaded onto the computer 300 and executed by the user as described below to create the mapping and imagery content data that is transferred to the control unit 230 (and eventually projected by the projector apparatus 220). The computer stored the software 250 in its internal memory and the user uses the associated interfaces and data files of the video compositing application. As described more fully below, the computer 300 can be connected to the Internet 400 to connect to a video content provider in order to purchase and download video projection clips (i.e., video data files) for projection on their architecture.
(84) Referring now to
(85) Beginning with
(86) The software 250 is then loaded onto the computer 300, which in this embodiment is a laptop computer. As used herein, a computer can be any electronic device (or combination of devices) having a display and the processing capabilities necessary to execute the software 250 and performing the necessary data communication, transfer and/or storage. For example, and without limitation, the computer 300 can be a television, a set-top cable box, a video game system, the control unit 200 and/or combinations thereof.
(87) The software 250 can be loaded onto the computer 300 via a computer readable medium or downloading through a WAN. All of the necessary power and data communication cables 240 are then installed so that the computer 300, the control unit 230 and the projector apparatus 250 are powered and communicate with one another, as established in

(93) As a result of properly sizing, shaping, positioning, and orienting the blank mattes 271-273 within the interface 254 as discussed above, the projected images of the mattes 271A-273A correspond to the real world surfaces 701-703 so that all of the edges of the projected images of the mattes 271A-273A coincide with the edges of the display surfaces 701-703 of the architecture 700. By this precise alignment, the edges of the projected matte images 271A-273A are invisible to a viewer and it appears as if the projected matte images 271A-273A perfectly conform to the display surfaces 701-703 respectively. Of course, and if necessary, the user can further fine tune the size, shape, position, orientation, or any combination thereof of the blank mattes 271-273 using real-world observation and comparative technique discussed above. Furthermore, once done creating mattes, the user can also use a corner pinning type tool to make sure that the optical distortion (if any) is compensated for.
(94) Referring now to
(95) Once the user selects the desired content file whose imagery he/she wants projected onto the architecture, the user associates the selected imagery content file with the desired matte 271-273. This can be done in any suitable way, such as a drag-and-drop technique or traditional command association.
(96) In the example, three different symbols 281-283 (static content files) have been added to the mattes 271-273 as the desired imagery content. While the imagery content is exemplified as simple static symbols, the invention is not so limited. The imagery content can include, without limitation, still photographs, video clips, still digital images, streaming digital video, movies, or any other visual content.
(97) Because the projection angle of the projector apparatus 220 is not normal to the non-coplanar and non-adjacent display surfaces 701-703, the projection of the imagery content on the display surfaces 701-703 will experiences substantial optical distortion if not connected. While the projection of the imagery content would be visibly distorted, it should be noted that the imagery content would still be properly aligned with and overlays the display surfaces 701-703. This is because the projection of the imagery content is limited to the space within the projected images of the mattes 271A-273A, which were sized and oriented in the steps described above.
(98) The optical distortion of the projected imagery content 281A-283A on the display surfaces 701-703 can be fixed by the user adjusting the internal properties of the mattes 271-273 to compensate for the optical distortion. This is done by using tools within the video compositing application, including, without limitation, rotating, scaling, corner pinning, general positioning, skewing, or any combination thereof. Adjusting the internal properties of the mattes results in a corresponding change in how the imagery content is projected onto the display surfaces in real time. As mentioned above, this is made possible by using the live video preview function of the video compositing application. Such correction would be especially effective when utilizing text imagery in the projections.
(99) This completes the mapping and content selection procedure. The general layout of the interface 255 (i.e. the map), including the matte coordinates and the internal properties of each matte can then be saved either internally or on an external memory device. The user can then utilize the saved map in the future to insert any piece of imagery content and/or change the imagery content as desired. As a result, the user can easily change the imagery content to be projected onto the architecture 700 without having to go through the mapping procedure by simply inserting new imagery content into the mattes. The internal matte properties will automatically be applied to the new imagery content.
(100) Once the map and desired imagery content is inserted into the mattes, a loop is designed and rendered within the video compositing application to effectuate continuous play of the imagery content. This data, including the looped imagery content, is compressed, e.g., in a mpeg-2 format, and then transmitted to the control unit 230 for internal storage. The control unit can store the data either internally or read it from an external memory device (see
(101) Once the control unit 230 has the necessary data, the control unit is switched to a display mode wherein the data (including the map and associated imagery content) is retrieved and projected onto the architecture 700 in a looped fashion via the projector apparatus 220. Once the user has created a composition and is ready to create their own customized loop or “mix” they then tell the program to compile or render and the CPU in the head unit compiles and flattens the mix into a single playable file, Once this file is compiled, it is playable via a playlist/playback application that the user can control from their laptop/phone/remote etc. The user than switches the head unit to playback mode and uses this for playback.
(102) System and Method of Content Distribution and/or Display
(103) Referring now to
(104) A user using the image projection kit 200 as described above will want to change their imagery content often, for example, depending on the event at the user site and/or the time of year. Using the content distribution system 1000, the user can build a very large library of projection clips and other imagery files for projection.
(105) The user's computer 300 is connected to a WAN, such as Internet 400, which is in turn connected to a large number of end computers 301-303. A content server 1310 is provided that stores a large number of content files (e.g., projection clips) that are created either in a studio 1320 or uploaded and stored on the server 1310 by other users via their computers 301-303. Of course, content uploaded by other users via their computers 301-303 should be monitored and/or censored as appropriate. The large number of content files stored on the server 1310 are made accessible, searchable, viewable and downloadable to the end user's computer 300 via a website or other electronic access point.
(106) The website has the proper interfaces and databases necessary to store and authenticate a user's information, identity and/or financial information. For example, a user may be required to enter her/his credit card information to create an account. The account will be assigned a user ID and a password. The website charges a fee for each projection clip downloaded by the user. The fee can be charged to a standing account that is set up by the user or on a single-purchase basis.
(107) While the invention has been described and illustrated in sufficient detail that those skilled in this art can readily make and use it, various alternatives, modifications, and improvements should become readily apparent without departing from the spirit and scope of the invention. For example, entirely different and unrelated imagery content can be inserted into different mattes for simultaneous projection onto different surfaces of the same architecture. Moreover, the invention is not limited to any specific software but can be carried out on any software application capable of carrying out the aforementioned functions.
