DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
(11) Please refer to following embodiments for details of structure and technical features of the present invention.
(12) Refer to FIG. 1, a shooting training and game system with virtual targets 1 of the present invention includes a main controller 10, a projection module 20, a lens module 30, and a shooting tool 40. Due to system control functions of the main controller 10 (such as hardware, software or firmware preset in the system 1), a light beam emitted from a light source (not shown in figure) is deflected and projected by the projection module 20 to form a virtual target image area 21 on a screen 2 (such as a white wall). The screen 2 is in front of the projection module 20 and there is a certain distance between the screen 2 and the projection module 20. The images shown on the virtual target image area 21 includes static virtual targets (as shown in FIG. 4-5, FIG. 6-7 and FIG. 8-9) or dynamic virtual targets (as shown in FIG. 2).
(13) While the system 1 of the present invention is used as a game system, the screen 2 is preferred, but not limited to, a white wall. The screen 2 is not necessary to be flat completely. For example, a projecting area 201 is formed on the screen 2 or a barrier 202 is arranged in front of the screen 2, as shown in FIG. 1. As long as the projecting area 201 and the barrier 202 will not affect user's (shooter's) vision (seeing/aiming). The image (virtual target) projected on the target image area 21 by the projection module 20 can also be projected on the surface of the projecting area 201 or the barrier 202. Thus the user (shooter) can also see (watching/aiming) the virtual target.
(14) The lens module 30 is aligned with the virtual target image area 21 for detecting and obtaining relative positions and coordinates of each shot 41 (as shown in FIG. 2, FIG. 4, FIG. 6 and FIG. 8) on the virtual target image area 21. Thereby the system 1 calculates the error of each shot 41 and used the error for evaluation of shooting accuracy (as shown in FIG. 2 to FIG. 9 and the details are described in the following). Each shot 22 (41) (as shown in FIG. 5, FIG. 7 and FIG. 9), error (as shown in FIG. 7) or shooting status of each target (as shown in FIG. 3 and FIG. 9) can also be projected and shown on the target image area 21 by the projection module 20. Thereby the shooting training and game system of the present invention is more optional, interesting, and having higher efficiency.
(15) As shown in FIG. 1, the shooting tool 40 includes a real gun and a laser gun. The shots 41 formed on the target image area 21 consist of bullet holes of the real gun and visible/invisible light spots emitted from the laser gun.
(16) When the shooting tool 40 is the laser gun, invisible infrared laser pulse (IR laser pulse) or visible laser light is emitted from the laser gun 40 to the target image area 21 to form invisible light spots or visible light spots. In an embodiment of the present invention, the wavelength of the laser light is ranging from 785 nm to 808 nm and no more than 808 nm. The duration of the laser light is no less than 0.1 second (≧0.1 sec.). Moreover, the distance between the target image area 21 of the screen and the projection module 20 can be, but not limited to 2.5 m. The projection module can be a microelectronic mechanical systems (MEMS) scanning module.
(17) Refer to FIG. 1, the projection module 20 is selected from the group consisting of a MEMS scanning module, a liquid, crystal display (LCD) module, a digital light processing module, and a galvanometric scanner module. In a preferred embodiment of the present invention, the projection module 20 is the MEMS module.
(18) In an embodiment of the present invention, the virtual target projected on the target image area 21 by the projection module 20 includes at least one static virtual target (a static target 24 shown in FIG. 6) or a dynamic virtual target (a moving target 23 shown in FIG. 2). The static virtual target is defined, as the virtual target projected on the target image area 21 that is at one fixed point while the dynamic virtual target is defined as the virtual target projected on the target image area 21 that is moved continuously. Moreover, when the virtual target projected having a plurality of targets is shown in different positions non-periodically (such as a plurality of targets 24 in FIG. 8), the targets can be either static or dynamic.
(19) Refer to FIG. 1, the projection module 20 and the lens module 30 are mechanically connected to and fixed by each other to form a solid object 3. And the detection area of the lens module 30 is aligned with or nearly equal to the target image area 21 projected by the projection module 20. Thus the lens module 30 can detect and obtain relative positions and coordinates of each shot 41 on the virtual target image area 21 formed by the shooting tool 40.
(20) As shown in FIG. 1, the main controller 10 can be a mobile Android device such as a smart phone, a tablet computer, etc. Thus the shooting game system of the present invention can be preset with software or firmware required by the device for users to select and use. Android is a mobile operating system (OS) based on the Linux kernel.
(21) Refer to FIG. 2, the virtual target projected on the target image area 21 by the projection module 20 is a moving target 23. In the figure, each moving target 23 is a moving green circle formed by projection of green-colored laser light. When the user shoots the moving target 23 by the shooting tool 40 such as a real gun/or laser gun and the shot 41 falls on the moving target, a sign of “HIT” that represents the target is hit is projected on the target image area 21 by the design of hardware, software or firmware set in the main controller 10 or the system 1, as shown in FIG. 3. Back to FIG. 2, the moving target 23 is not hit on the first three shots 41. With the last one shot 41, the shooter hits the moving target 23.
(22) Refer to FIG. 4, the shooting tool 40 shots and a plurality of shots 41 is formed on the target image area 21. Then the lens module 30 detects and gets relative positions of each shot 41. In the figure, there are six shots 41 and the shooting tool 40 is the laser gun. When the laser gun 40 shots the target image area 21 by invisible light such as IR laser pulse to form a plurality of invisible shot 41, the user can choose a capture mode of the lens module 30 and a shot display mode of the projection module 20. Thus the projection module 20 projects visible laser light such as green laser light to show visible shots 22 at the positions corresponding to the shots 41 on the target image area 21 after the lens module 30 detecting and obtaining relative positions (or coordinates) of the invisible shots 41, as shown in FIG. 5. Therefore the user can check accuracy of each shot by the vision. The shooting game has more options and more interest. Moreover, the shooting tool 40 can be a real gun or a laser gun. The main controller 10 or the system 1 of the present invention is preset with hardware, software or firmware that is corresponding to a selection key or a switch key. Thus users can select or switch to different modes by the selection key or the switch key. For example, the capture mode of the lens module 30 or the shot display mode of the projection module 20 can be selected by the keys mentioned above.
(23) Refer to FIG. 6 and FIG. 7, the virtual target projected on the target image area 21 is a static, fixed target 24. The target 24 is a green dart board having a center point 25. When the user shots the fixed target 24 by using the shooting tool 40 and the shot 41 falls around the center point 25 of the fixed target 24, the fixed virtual target 24, the shot 22 (41) and an additional shooting score (such as error) 26 are shown on the target image area 21 by the projection module 20 due to the design of hardware, software or firmware preset in the main controller 10 or the system 1. Therefore the shooting game is more interesting. As shown in FIG. 7, 21 cm in the figure represents the distance between the shot 22 (41) and the center point 25 of the fixed target 24. The shooting score 26 is calculated and shown as a preset score corresponding to the distance. The additional shooting score 26 can also be calculated by the hardware, software or firmware preset in the main controller 10 or the system 1 with reference to other parameters (such as the distance between the screen 2 and the projection module 20).
(24) Refer to FIG. 8 and FIG. 9, there is a plurality of virtual target 24 projected on the target image area 21. As shown in FIG. 8, there are six targets 24 each of which is a green circle formed by projection of green laser light. There are several display modes of the targets 24. For example, the six targets 24 can be shown at the respective position simultaneously for users to shot one after another. Or the six targets 24 are displayed in turn and users can change aiming point quickly along with the jumped target 24. The targets 24 in FIG. 8 can be static virtual targets or dynamic virtual targets.
(25) Furthermore, refer to FIG. 8 and FIG. 9, when a plurality of targets 24 is formed by the shooting tool 40 and is fallen in the target 24, a burst figure 27 can be shown at the shot target 24 on the target image area 21 by the projection module 20 due to the hardware, software or firmware preset in the main controller 10 or the system 1. For example, there are 3 of the 6 targets 24 being shot and shown with the burst figure 27. The shooting/game system is more interesting.
(26) In addition, the hardware, software or firmware can be preset in the main controller 10 according to requirements of the system 1. For example, the main controller 10 of the present invention can be a mobile. Android device such as a smart phone, a tablet computer, etc. Moreover, a Bluetooth-enabled MEMS controller is also used to control the projection module 20 formed by MEMS. The Bluetooth-enabled MEMS Controller is included in the main controller 10.
(27) Additional advantages and modifications will readily occur to those skilled in the art. Therefore, the invention in its broader aspects is not limited to the specific details, and representative devices shown and described herein.
