Abstract

The invention provides a method and device for determining whether a laser radar breaks down or not, a processor and a vehicle. The method comprises the steps of obtaining a first signal of the laser radar in operation in real time, wherein the first signal comprises a first sound signal and/or a first vibration signal; obtaining a preset signal range, wherein the preset signal range comprises a first preset signal range and a second preset signal range, the first preset signal range is a range formed by a maximum sound signal and a minimum sound signal of the laser radar under the fault-free condition, and the second preset signal range is a range formed by the maximum vibration signal and the minimum vibration signal of the laser radar under the fault-free condition; and determining whether the laser radar has a fault or not according to the first signal and the preset signal range. According to the method, whether the laser radar breaks down or not can be pre-judged, it is guaranteed that potential faults of the laser radar can be found in time, follow-up troubleshooting and overhauling are facilitated, and the problem of safety accidents caused by the faults of the laser radar is avoided.

Description

technical field [0001] The present application relates to the field of laser radar, in particular, to a method, device, computer-readable storage medium, processor, electronic equipment and vehicle for determining whether the laser radar is faulty. Background technique [0002] At present, mechanical LIDAR (Light-Detection-And-Randing, laser radar) is widely used in unmanned vehicles, but if the mechanical LIDAR is used for a long time in the harsh operating environment of the vehicle, it is prone to damage and dangerous accidents . Therefore, there is an urgent need for a method for real-time monitoring of the working conditions of the mechanical LIDAR to ensure the safety and reliability of the unmanned driving system. [0003] The above information disclosed in the Background section is only to enhance the understanding of the background of the technology described herein, therefore, the Background may contain certain information which is not formed in the country for th...
