Abstract

The invention discloses a VR positioning method, device and system. The method comprises steps that at least one synchronization signal is obtained by a receiving terminal at the first time segment, at least one scanning signal transmitted by scanning base stations is obtained at the second time segment, the at least one synchronization signal and the at least one scanning signal are classified, the synchronization signals and the scanning signals belonging to the same scanning base stations are determined, according to the obtaining time of the synchronization signals and the obtaining time of the scanning signals of the same scanning base stations, and the scanning speed of the scanning base stations, the position of the receiving terminal is determined. The method is advantaged in thatthe method is suitable for VR large space positioning, the scanning base stations corresponding to the scanning signals received by the receiving terminal can be determined by the receiving terminal,and the scanning signals of the scanning base stations do not interfere with each other.

Description

technical field [0001] Embodiments of the present invention relate to the technical fields of laser and electronics, and in particular to a VR positioning method, device and system. Background technique [0002] In order to improve the user experience of virtual reality (VR) large-space applications, VR positioning technology has higher and higher requirements for positioning accuracy, real-time performance, and spatial scalability. Due to its monochromatic and directional characteristics, laser is one of the main technical means to achieve precise positioning of targets. [0003] The current VR laser positioning mainly uses dual base stations (master-slave base station, when the master base station is working, the slave base station is off, and vice versa), each base station is equipped with a laser scanning module to scan the scanning area, and it can achieve good results within its coverage. positioning experience. However, the existing positioning technology has a smal...
