Problems solved by technology

[0007] The existing problem is that when the existing multimedia interactive projection system is working, the infrared emitter is usually fixed, so the infrared rays are emitted from a fixed point. Specific operating parts produce light spots (such as finger parts), but other parts of the body may be between fingers and infrared emitters, earlier contact and block infrared rays, resulting in wrong light point coordinate data, which affects multimedia interactive projection The accuracy of the system, and the projection surface is often of different materials, the simple fixing method is easy to cause the infrared emitter to fall off, if the projection surface is uneven, if the simply fixed infrared emitter is in the depression, it will not be completely Cover projection surface

Description

technical field [0001] The invention relates to a multimedia interactive projection system, in particular to a signal transmitting device of the multimedia interactive projection system. Background technique [0002] The multimedia interactive projection system is based on the motion tracking technology, which is a multimedia technology that interacts and feeds back the actions of the interactive participants and the projected images. Existing multimedia interactive projection systems usually include an imaging module, a signal transmitting module, a signal collecting module, and a signal processing module. [0003] Imaging modules usually use projectors or other imaging devices to project images on specific locations, such as walls, curtain surfaces, glass panels, etc. In addition to projectors, imaging devices include plasma displays, liquid crystal displays, and LED screens. can be used as the carrier of interactive images; [0004] The signal emission module usually us...
