Abstract

Embodiments of the present invention provide a lidar temperature compensation method, device, system and equipment, the method comprising: acquiring the initial temperature of the lidar; determining the initial control voltage and pulse width corresponding to the initial temperature; according to the acquired real-time temperature, and determine a corresponding real-time control voltage, so that the laser radar emits a laser pulse with the pulse width by adjusting the initial control voltage. Through the above technical solution, by adjusting the control voltage, the influence of the real-time temperature change of the laser radar on the pulse width is compensated, so that the pulse width of the laser pulse remains unchanged. response speed.

Description

technical field [0001] The invention relates to the technical field of lidar control, in particular to a lidar temperature compensation method, device, system and equipment. Background technique [0002] Lidar converts electrical pulses into laser pulses and emits them, and the optical receiver converts the laser pulses reflected from the target into electrical pulses and sends them to the display. The pulse width of the laser pulse emitted by the laser radar is easily affected by the temperature of the laser radar device. Under the same control voltage, the pulse width of the laser pulse generated when the device temperature is different is also different. [0003] In the prior art, in order to avoid the influence of the temperature change of the LiDAR equipment on the measurement results, it is usually necessary to warm up the LiDAR for a period of time, and then measure when the pulse width reaches a stable state. In different usage environments, the time required for th...
