Abstract

An embodiment of the invention discloses a laser radar anti-interference method, laser radar and a vehicle. The laser radar anti-interference method includes: monitoring whether ambient light intensity of a current environment is larger than a preset threshold or not; if yes, emitting at least two detection pulse laser beams by a first frequency; in received light, determining echo light beams, reflected by a target object, of the detection pulse laser beams, wherein the received light comprises the echo light beams, reflected by a target object, of the detection pulse laser beams, echo lightbeams, reflected by a target object, of ambient light and the ambient light. By the technical scheme in the embodiment, the problem that laser radar measurement accuracy is affected by the ambient light is solved, and the anti-interference performance of the laser radar is effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to laser radar technology, and in particular to a laser radar anti-jamming method, laser radar and a vehicle. Background technique [0002] Lidar is a radar system that uses laser to detect the position, speed and other characteristic quantities of the target. Its working principle is to first transmit the detection laser beam to the target, and then compare the received signal reflected from the target with the transmitted signal, and make an appropriate After processing, information such as the distance, orientation, height, speed, attitude, and even shape of the target can be obtained, which is widely used in the fields of automobile assisted driving or automatic driving, service robots, and industrial automation. [0003] In automotive technology, with the popularization and application of on-board lidar, the interference problem between lidars on different vehicles is becoming more and more serious. Whe...
