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...

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0032] A laser measurement device, such as a laser radar or a laser rangefinder, is a perception system for the outside world, which can obtain three-dimensional three-dimensional information of the outside world, and is no longer limited to the plane perception of the outside world such as cameras. The principle of the laser measurement device can be to actively emit laser pulse signals to the outside, detect the reflected laser pulse signals, judge the distance of the measured object according to the time difference between emission and reception, and then combine the emission angle information of the light pulses, it can be Reconstruction acquires 3D depth information.

[0033] The measuring distance that the laser measuring device can achieve is related to the power of the...
