Problems solved by technology
[0004] The inventor found in the research that the laser positioning method in the related art is limited by the range of the laser so that the positioning space is in a small range (generally around 5*5*2m range), and the connection of multiple above-mentioned positioning spaces There is mutual interference between lasers, which makes it impossible to perform accurate spatial positioning in a large range corresponding to multiple positioning spaces, and the applicability is poor

The invention provides a wireless positioning synchronization system and a positioning system. The wireless positioning synchronization system comprises a signal emission device and a control device; the signal emission device comprises a first emission group containing at least one first emission source and a second emission group containing at least one second emission source; the control device controls the first emission sources to synchronously emit first optical signals and controls the second emission sources to synchronously emit second optical signals a preset time interval after controlling the first emission sources to synchronously emit the first optical signals; the first emission frequency band occupied by the first emission sources and the second emission frequency band occupied by the second emission sources do not overlap; and the coverage ranges of the first optical signals and the coverage ranges of the second optical signals overlap, the coverage ranges of the first optical signals do not overlap, and the coverage ranges of the second optical signals do not overlap. According to the wireless positioning synchronization system and the positioning system, widening of the space positioning range and precise positioning in the positioning space are achieved, and the VR experience degree of a user is improved.
Description
technical field [0001] The present invention relates to the technical field of positioning, in particular to a positioning wireless synchronization system and a positioning system. Background technique [0002] At present, with the continuous development of social productivity and science and technology, all walks of life pay more and more attention to the research of virtual display (Virtual Reality, VR) technology, VR technology has also made great progress, and gradually become a new field of science and technology. Among them, VR spatial positioning is a key link in VR technology. [0003] A laser positioning method is proposed in the related art. When performing spatial positioning, the method generally sends a laser scanning signal to a positioning terminal (such as a head-mounted display, an operating handle, etc.) through a positioning base station, and then receives the laser scanning signal according to the positioning terminal. The time difference determines the ...
