The invention discloses a target positioning method and device using laser scanning. The method includes the following steps: acquiring first coordinates of first laser receiving devices scanned by alaser scanning base station in a world coordinate system; determining first relative position relationships between a preset positioning point in a to-be-positioned target and the first laser receiving devices in a local coordinate system of the to-be-positioned target; determining first corrected position relationships of the first relative position relationships under the world coordinate systemaccording to the attitude information of the to-be-positioned target; and finally, determining a third coordinate of the positioning point in the world coordinate system according to the first coordinates and the first corrected position relationships, and taking the third coordinate as the location of the to-be-positioned target. Thus, the problem of alignment jitter in the 3D spatial location of the to-be-positioned target caused by different positioning results of multiple laser receiving devices in the prior art can be solved, and the positioning accuracy of the to-be-positioned target isimproved.
Description
Technical field[0001]The invention relates to the field of laser and electronic technology, and in particular to a target positioning method and device using laser scanning.Background technique[0002]Virtual Reality (VR) technology is a technology that uses a computer to generate a simulated environment, and with the help of professional equipment, allows users to enter a virtual space, perceive and operate in real time, thereby obtaining an immersive experience.[0003]The most important feature of VR technology is its sense of immersion, and a set of high-precision and real-time three-dimensional positioning system is an important part of achieving this feature. The accuracy of the laser positioning solution can reach the millimeter level, which is currently the realization of VR positioning. One of the main technical means. Among them, the basic principle of laser positioning is to use laser scanning base stations to emit horizontal and vertical scanning lasers into the detection sp...
