Method for unifying coordinate systems of positioning base stations and positioning calibration device

Abstract

The embodiment of the invention provides a method for unifying coordinate systems of positioning base stations and a positioning calibration device. The positioning calibration device obtains first coordinates of at least three laser receiving modules in a coordinate system of a first positioning base station and second coordinates of the at least three laser receiving modules in the coordinate system of a second positioning base station, at the same time. The first positioning base station is taken as a reference, and the positioning calibration device determines orientation postures of the second positioning base station in the coordinate system of the first positioning base station according to the first coordinates of the at least three laser receiving modules in the coordinate system of the first positioning base station and the second coordinates of the at least three laser receiving modules in the coordinate system of the second positioning base station. Coordinates of a target object in two coordinate systems can be unified according to the orientation postures of the second positioning base station in the coordinate system of the first positioning base station, so the user experience is prevented from being influenced due to positioning jitter of the target when the same target is monitored by two different positioning base stations, inertial sensors do not need to be added to the positioning base stations additionally, and the hardware cost is saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical fields of laser and electronics, and in particular, to a method for uniformly positioning a coordinate system of a base station and a positioning calibration device. Background technique [0002] Virtual Reality (VR for short) technology is a technology that uses a computer to generate a simulated environment, and with the help of professional equipment, allows users to enter the virtual space, perceive and operate in real time, so as to obtain an immersive real experience. At present, the VR industry is in the start-up period. As a large number of VR devices have been mass-produced in the past two years and pushed to the consumer market, the industry is about to enter a period of rapid development. [0003] The most important feature of VR technology is its sense of immersion, and a positioning system with high precision and good real-time performance is an important part of realizing this f...
