Laser emitting device for three-dimensional positioning

Abstract

The invention discloses a laser emitting device for three-dimensional positioning. The laser emitting device comprises a laser emitting rotating device, a control circuit board, a mounting base and atransparent shell. The laser emitting rotating device comprises a motor and laser emitting parts. The control circuit board controls the rotating speed of the motor, and the motor drives the laser emitting device to rotate so as to achieve 360-degree laser coverage.

Description

technical field [0001] The invention describes a laser emitting device for three-dimensional space position and posture positioning. Background technique [0002] With the development of artificial intelligence robots and intelligent manufacturing, the demand for high-precision three-dimensional pose positioning is increasingly strong. At present, the solutions that can achieve high-precision three-dimensional positioning at the submillimeter level are mainly infrared images and lasers. The former is represented by Optitrack and vicon, but the cost is very high and there is serious delay. The latter is represented by the lighthouse technology developed by the game company Valve, which is mainly used in the field of virtual reality. The lighthouse technology scheme uses two high-speed rotating motors to emit lasers in both horizontal and vertical directions, and uses infrared flashlights for flash synchronization. There are two problems with this solution. One is that the t...

Problems solved by technology

There are two problems in this solution. One is that the two high-speed rotating motors bring internal high-frequency vibrations, which makes the laser rotor filter algorithm unable to handle small high-frequency vibrations, which limits the improvement of positioning accuracy.

Second, infrared flash synchronization limits the increase in the number of base stations that can be connected and the effective range of a single base station
