Power adjustment method and laser measurement apparatus

Abstract

Embodiments of the present invention provide a power adjustment method and a laser measurement apparatus, wherein the method includes: controlling a power detection circuit to detect the power of a laser emitted by a laser emission circuit; acquiring a threshold power corresponding to a laser measurement device; and according to the threshold power, adjusting the power of the laser emitted by thelaser emission circuit. The power of the laser emitted by the laser measurement device can be intelligently adjusted to improve the performance of the laser measurement device.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a power adjustment method and a laser measuring device. Background technique [0002] Laser measurement devices (such as lidar) are perception systems for the outside world, which can obtain three-dimensional three-dimensional information of the outside world, and are no longer limited to plane perception methods such as cameras. The principle of the laser measurement device can be to actively emit laser pulse signals to the outside, detect the reflected pulse signals, and judge the distance of the measured object according to the time difference between emission and reception; combined with the emission angle information of the light pulse, it can be reconstructed. 3D depth information. [0003] Because the power of the laser emitted by the laser measuring device cannot exceed the threshold power. In the actual production process, before the laser measuring device leaves t...

Problems solved by technology

[0004] However, considering the inconsistency of components such as circuit devices, laser tubes, and optical structures, the power of different laser measurement devices in mass production will have certain differences. The output power of the laser measuring device will be small and the performance will be poor
