The invention discloses a virtual reality positioning system, comprising a laser emitting device and a virtual reality device; the laser emitting device is fixedly arranged at a predetermined position in a to-be-monitored area, the laser emitting device comprises M groups of emitting units, the M The single scan duration of a group of transmitting units for the area to be monitored is greater than the scan duration of any one group of transmitting units and not greater than the time T for one rotation of a laser rotating scanning device, and M is a positive integer greater than 1; wherein, each group transmits The unit includes three laser rotating scanning devices, and the receiving point on the virtual reality device can receive the laser signals emitted by the three laser rotating scanning devices, and then the virtual reality device realizes a positioning according to the received laser signals emitted by each group of transmitting units. , the three laser rotating scanning devices are activated in sequence and have different scanning periods for the to-be-monitored area, so as to solve the problem that the existing laser scanning method has an empty window period.
Description
technical field [0001] The invention relates to the field of virtual reality, in particular to a virtual reality positioning system. Background technique [0002] Virtual reality (Virtual Reality, referred to as virtual reality) is a high-tech that has emerged in recent years. Virtual reality uses computer simulation to generate a three-dimensional virtual world, providing users with simulations of vision, hearing, touch and other senses, allowing users to feel like Immersive generally, you can observe things in three-dimensional space in time and without limitation. [0003] The current virtual reality positioning system includes a virtual reality helmet and a laser positioning base station, wherein the laser positioning base station is generally a cuboid base station containing three laser rotating scanning devices inside, and is usually fixed at the corner of the room. The lasers are sequentially emitted in sequence to scan the room, so the laser surfaces emitted by the ...
