Abstract

The embodiments of the present invention disclose a method for anti-interference of a laser radar, a laser radar and a vehicle. The anti-jamming method for lidar includes: monitoring whether the light intensity of ambient light in the current environment is greater than a preset threshold; if so, transmitting at least two detection pulse lasers at a first frequency; determining in the received light that the detection pulse laser passes through the target object The reflected echo beam; wherein, the received light includes the echo beam reflected by the detection pulse laser by the target object, the echo beam reflected by the ambient light by the target object, and the ambient light. The technical solutions of the embodiments of the present invention solve the problem that ambient light affects the measurement accuracy of the laser radar, and effectively improve the anti-interference ability of the laser radar.

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...
