Abstract

The invention discloses a multi-base-station laser positioning method, system and device and a medium, and the method comprises the steps: controlling a plurality of base stations to emit laser to a to-be-measured object, enabling a laser receiving plate on the to-be-measured object to receive the laser, obtaining the position information of the laser on the laser receiving plate, and transmitting the position information of the laser to the to-be-measured object; the position information is sent to the corresponding base station; the base station adjusts the emission angle of the laser according to the position information until the laser irradiates a preset position on the laser receiving plate, and the emission angle corresponding to the preset position irradiated by the laser is recorded; and obtaining the space coordinates of the object to be measured according to the emission angles recorded in the plurality of base stations. According to the invention, a plurality of base stations are adopted to emit laser to the to-be-measured object, and remote and rapid positioning is realized in combination with signal feedback of the to-be-measured object; in addition, realized hardware equipment is low in cost and easy to popularize. The method can be widely applied to the technical field of space positioning.

Description

technical field [0001] The present invention relates to the technical field of space positioning, in particular to a multi-base station laser positioning method, system, device and medium. Background technique [0002] At present, positioning technology has become more mature and has been widely used. Mainstream positioning technologies, such as GPS system positioning, radio positioning, ultrasonic positioning, etc., have low precision and cannot meet the sub-centimeter level accuracy requirements. The existing laser positioning technology generally uses a motor to measure the angle, and the accuracy is low; the accuracy can be improved by combining image processing technology, but the algorithm is complicated; It is not easy to implement when it is far away, the target volume is small, and it involves multi-target positioning. Contents of the invention [0003] In order to solve one of the technical problems in the prior art at least to a certain extent, the purpose of ...
