Description

Technical Field

[0001] The utility model relates to the technical field of interactive projection, in particular to a camera-sensing interactive projection device. Background Art

[0002] At present, with the continuous development of the times, various types of entertainment games are emerging, such as projection games, including desktop projection games, ground projection games and wall projection games, and all of them are through the real-time combination of interactive sensing and image display. All special programs will make the image generation and interactive sensing change synchronously.

[0003] Projection technology is only dedicated to creating a virtual environment and placing the audience in this virtual environment. In existing ground projection games, the interactive projection device mainly uses a projector for projection and a camera to sense and identify the human body. After the human body is captured by the camera, the main control host will drive the projector to operate and form a projection to create a sense of human-computer interaction. However, due to the limited projection area of ​​the projector, when the interactive projection device is used in a corridor scene, in order to complete the projection of the entire ground curtain, there are usually multiple interactive projection components (especially projectors), and they are set at intervals. Each interactive projection component needs to be fixed to the indoor side wall with bolts. In later testing, it will be found that due to deviations in distance control, the projection displayed on the ground curtain will have too many intervals or overlapping areas, resulting in poor projection effects. Subsequently, it is necessary to disassemble and re-adjust the position of the interactive projection components. For this reason, a camera sensing interactive projection device is proposed.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] like Figure 1 and Figure 2 As shown, a camera-sensing interactive projection device in this embodiment is provided for users to play interactive ground projection games. The camera-sensing interactive projection device includes a positioning structure 1 and a plurality of interactive projection components 2, wherein the interactive projection component 2 includes a pan-tilt bracket 21, an infrared camera 22, a projector 23, a ground screen 24 and a sliding sleeve 25, and the positioning structure 1 includes an assembly frame 11 and a slide 12, and the slide 12 is used to provide a supporting surface and movable space support for the sliding sleeve 25 in each interactive projection component 2, so that the position of the projector 23 can be easily adjusted. In this way, when the interactive effect is tested later, when there is a gap or too much overlap between the projections emitted by two adjacent projectors 23 displayed on the ground screen 24, the position between the two sets of adjacent interactive projection components 2 can be directly adjusted by sliding, without the need for traditional disassembly and assembly procedures, and debugging can be completed quickly to improve the poor projection effect.

[0024] To facilitate understanding of the structure and positional relationship between the positioning structure 1 and the interactive projection component 2, further explanation is given. First, as Figure 1As shown, the assembly frame 11 and the slide 12 in the positioning structure 1 are both horizontally arranged, and the assembly frame 11 and the slide 12 are integrally fixedly connected. The assembly frame 11 is actually fixedly arranged on the indoor side wall by bolts, and the slide 12 is not only horizontally arranged, but also I-shaped, forming an upper slide groove and a lower slide groove. The number of interactive projection components 2 is preferably five groups, and the five groups of interactive projection components 2 are linearly distributed at equal distances. The sliding sleeve 25 in the interactive projection component 2 is fixedly arranged on one side of the pan-tilt bracket 21 close to the slide 12, and is movably connected to the slide 12 through the upper slide groove and the lower slide groove. In this way, the slide 12 can complete the support of all interactive projection components 2, and the position of the projector 23 can be conveniently adjusted.

[0025] In addition, it should be noted that the pan / tilt bracket 21, infrared camera 22, projector 23 and floor screen 24 are prior art, and the total projection area of ​​the five sets of projectors 23 does not exceed the laying area of ​​the floor screen 24. Figure 1 As shown, in this embodiment, the infrared camera 22 and the projector 23 are respectively fixed on the upper and lower sides of the pan-tilt bracket 21 by bolts, and the floor screen 24 is arranged below the projector 23. The working principle is to allow the infrared camera 22 to identify the person through infrared sensing, and the projector 23 projects the atmosphere image onto the floor screen 24 after the infrared camera 22 captures the person. In practice, the infrared camera 22 transmits the signal to the main control host (not shown in the figure), so that the main control host controls the projector 23 to project, for example, the water flow atmosphere image onto the floor screen 24.

[0026] Considering that the sliding sleeve 25 or the interactive projection component 2 is easily affected by external forces and changes in position, in order to enhance the anti-interference ability or stability of the interactive projection component 2 under normal conditions, further, as a preferred solution, Figure 2 As shown, a magnetic attraction area 3 is provided in the upper slide groove and the lower slide groove, and the slide sleeve 25 is made of metal, so that the slide sleeve 25 can be magnetically connected to the slide frame 12, that is, a magnet is fixedly provided in the slide sleeve 25, and the above-mentioned magnetic attraction area 3 is generated by the magnet, so that the stability of the interactive projection component 2 can be enhanced. In addition, it can be understood that the size of the magnetic force is determined according to the actual weight of the interactive projection component 2, but it is necessary to ensure that human hands can easily push it.

[0027] To ensure that the assembly frame 11 is horizontally arranged, Figure 1 As shown, the positioning structure 1 also includes a positioning strip 13. Bolt holes are provided on the front surface of the assembly frame 11 and the top surface of the positioning strip 13. The bolt holes are used to drive bolts. The positioning strip 13 is fixed to the assembly frame 11 and is L-shaped. The positioning strip 13 is arranged at the junction of the indoor side wall and the wall top, so that the upper surface of the assembly frame 11 can be parallel to the wall top.

[0028] In order to enhance the user experience and make it more realistic, a real spray effect is added on the basis of the virtual image of the projector 23, that is, a combination of virtual and real. Figure 1 and 3 As shown, the camera-sensing interactive projection device further includes a spray structure 4, which is disposed at the bottom of the slide 12 and is used for atomization spraying.

[0029] Further explanation, such as Figure 3 As shown, the spray structure 4 includes an extension frame 41, a pipe rack 42, a water pipe 43 and an atomizing nozzle 44, wherein the pipe rack 42 is arranged below the slide 12, the extension frame 41 is fixedly arranged between the slide 12 and the pipe rack 42, the atomizing nozzle 44 is threadedly connected to the bottom of the water pipe 43, the water pipe 43 is fixedly arranged on the inner side of the pipe rack 42 and is connected to the indoor water pipe, and a valve body is assembled on the outer side of the water pipe 43 for controlling whether the water pipe 43 can be conducted.

[0030] In this way, when working, based on the projection produced by the projector 23, the valve body can be opened to allow water in the indoor water pipe to enter the water pipe 43, and finally the water is sprayed out from the atomizing nozzle 44, thereby increasing the interactive effect and improving the user experience.

[0031] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
