Disclosed herein is a method for generating a composite image, including using at least one hardware processor for obtaining at least two images; obtaining composite spatial data that identifies contiguity characteristics of each image of the at least two images; generating a template of the composite image, wherein the template provides a predetermined arrangement of the sections according to the contiguity characteristics identified in the image; sectioning the at least two images into predetermined number of sections according to the template; splicing the sections together according to the template; generating the composite image from the sections of the at least two images; wherein presence of at least one contiguity characteristic in each image generates an composite image that is ambiguous that can trigger an alternating switch in perception and awareness of each image scene and by establishing figure and ground relationship to create a depth illusion.

The invention relates to a method and to a device for displaying a three-dimensional scene on a display surface having an arbitrary non planar shape, for correct viewing by an user having a given position in a three-dimensional spatial reference system. The method comprises displaying a display image comprising pixels which represent the three-dimensional scene. The invention comprises: a first step (A1) of projecting a three-dimensional model of the display surface onto a projection plane (P.sub.L) in perspective, the projection in perspective having a projection centre which is dependent on the position of the user in the spatial reference system, making it possible to obtain a projection image (I.sub.proj) of the display surface from the point of view of the user; and a second step (A2) of calculating a projection of the three-dimensional scene on the display surface using said projection image (I.sub.proj).

A 3D coordinate measuring system includes a six-DOF unit having a unit frame of reference and including a structure, a retroreflector, a triangulation scanner, and an augmented reality (AR) color camera. The retroreflector, scanner and AR camera are attached to the structure. The scanner includes a first camera configured to form a first image of the pattern of light projected onto the object by a projector. The first camera and projector configured to cooperate to determine first 3D coordinates of a point on the object in the unit frame of reference, the determination based at least in part on the projected pattern of light and the first image. The system also includes a coordinate measuring device having a device frame of reference and configured to measure a pose of the retroreflector in the device frame of reference, the measured pose including measurements of six degrees-of-freedom of the retroreflector.

A system and method for manipulating images in a videoconferencing session provides users with a 3-D-like view of one or more presented sites, without the need for 3-D equipment. A plurality of cameras may record a room at a transmitting endpoint, and the receiving endpoint may select one of the received video streams based upon a point of view of a conferee at the receiving endpoint. The conferee at the receiving endpoint will thus experience a 3-D-like view of the presented site.

Data comprising a compressed image frame and temporal redundancy information is received. The image frame is decompressed. A plurality of bridge frames that are visually dissimilar to the image frame are generated. The image frame and the plurality of bridge frames are blended, generating a plurality of blended frames, and the plurality of blended frames are displayed.

A display system adapted to use rapid switching techniques to switch between displaying content and displaying a mask for that content so as to provide per-pixel opacity control. The display system may employ rapid synchronized switching of both a non-emissive, transparent display and a transparent backlight. In a first state, the display is operated to display content with the backlight acting as a scattering luminous backlight. In the other or second state, the display is operated to display one or more masks (for some or all objects or items of the content displayed in the first state) with the backlight functioning as a clear and unlit backlight. The display system is capable of producing opaque emissive content on a transparent field to provide a novel display and/or for use in compact spatial augmented reality applications.

A naked-eye 3D image forming method. The method includes: determining an outline coordinate of display image of display device in a vertical plane; determining a coordinate of an observation point R including height h, and distance l; inclining the display device toward the horizontal plane to obtain a tilt angle ; according to coordinates of the two points of the original image on the horizontal plane, the height h, length l and angle to calculate an outline coordinate of a present image; according to all coordinate points contained by the outline coordinate of the preset image, the height h, the length l and the tilt angle to calculate projection coordinate points on the display screen; converting the projection coordinate points into digital signals and inputting to the image expanding control module such that the display device forms the preset image on an image on the vertical plane.

This fully-automated 3D photo booth uses a single-or dual-lens camera or other depth sensors. Depth algorithms process the pictures taken, which can be inserted into themed templates. A novel method of coarse segmentation separates the foreground and background. The photo booth dispenses an interlaced print and snap-in photo frame, or gives the option of viewing on a mobile device or sending via email or social media. On a mobile device, the 3D viewing is with a snap-on or adhesive optical overlay if available, using novel lenticules that solve Moir artifacts. In the absence of an optical overlay, tilt sensors are used to move the viewpoint of the 3D scene model, to look around objects in the foreground, the same as if real objects were being tilted back and forth.

A presentation device according to the present invention includes a panel-shaped image-forming optical element and a flat panel display, and forms a video picture (image) appearing on the display as a spatial image in space over the image-forming optical element. Between the upper surface of the image-forming optical element and the spatial image, a plate (guide plate) having an opening corresponding to the planar shape of the image-forming optical element is disposed at an attitude inclined upwardly from the front toward the back side with respect to the image-forming optical element, whereby the spatial image floats up through the opening of the guide plate. This allows anyone to view a three-dimensional spatial image rich in a sense of depth without experience and skill automatically in an appropriate direction from an appropriate position.
