Embodiment 1

[0039] A device for implementing multimedia exhibits, such as figure 1 As shown, it includes a processor, a camera 4, a projector 5, a rear projection 2 and a baffle 3; the projector 5 is projected onto the rear projection 2, and the processor is used to receive and process the data collected by the camera 4; the camera 4 is set in the projection The top of the instrument 5, the camera 4 is provided with a supplementary light, and the camera 4 is also provided with a 1mm filter; the processor is generally a computer connected to the device.

[0040] Such as figure 2 As shown, the rear projection 2 is a glass plate, the rear projection 2 is covered with a holographic film 21 on the side close to the projector 5, the rear projection 2 is provided with a barbed wire 22 on the side away from the projector 5, and the other side of the barbed wire is provided with a baffle 3 , The baffle plate 3 is a magnetic force plate.

[0041] Start the device, the projector 5 projects the sc...

Embodiment 2

[0045] The solution of embodiment 2 is basically the same as that of embodiment 1, the only difference is that the field of view of the camera is consistent with the projection range of the projector.

[0046] These two ranges should be consistent as much as possible, so that the position tilt information of the baffle on the glass can coincide with the information of the baffle collision body projected by the projector, and there will be no coordinate deviation, thereby greatly improving the detection accuracy of the device.

Embodiment 3

[0048]The scheme of Example 3 is basically the same as that of Example 2. The only difference is that the holographic film is milky white or light gray. The contrast between milky white and light gray and the shadow is obvious, which is beneficial to the software to detect the position coordinates of the baffle. Most of them are transparent on the market. , light gray, dark gray, milky white, the contrast between light gray and milky white is obvious, and the image projected by the transparent rear projection is relatively unclear. In addition, no sundries should be placed on the glass to affect the test results.

Abstract

The invention discloses a device and a method for realizing multimedia exhibition items, belonging to the field of multimedia. Its equipment includes a processor, camera, projector, rear projection and baffle; the camera is arranged on the top of the projector, and the camera is provided with a 1mm filter; One side of the projector is covered with a holographic film, the rear projection is provided with barbed wire on the side away from the projector, and the other side of the barbed wire is provided with a baffle. The method of using the device to realize multimedia exhibition items, using the camera to obtain the shadow map of the baffle and filter out the interference, to obtain the white pixel block; sampling and extracting the position information of the white pixel block; performing coordinate conversion; generating a collision body according to the converted coordinates interact. The present invention not only has simple equipment and low cost, but also has high detection accuracy in game experience. The method for realizing multimedia exhibition items based on the equipment of the present invention can effectively obtain the position information of the baffle, greatly simplifies the processing steps, and accurately detects result.

Description

technical field [0001] The invention belongs to the field of multimedia, and in particular relates to a device and a method for realizing multimedia exhibition items. Background technique [0002] The great progress of digital display technology brought by computer technology has been applied in all aspects. Among them, the digital display center based on computer technology can use advanced computer vision technology and projection display technology to create a fantastic and dynamic interactive experience and realize multimedia exhibition items. ;Integrate the display content into a digital multimedia exhibition item and digital content display, and create a display hall with distinctive personality with novel display concepts, super digital content creativity, and intelligent technological means. [0003] At present, the exhibition hall is biased towards the experience of visual effects, and its interactive content is relatively small. Some of them only stay in relatively...
