Problems solved by technology

[0003] However, during the driving process of the vehicle, there will inevitably be body shaking, which will easily cause slight changes in the position of the lidar, invalidate the calibration parameters, and affect the driving state of the vehicle. Therefore, the position of the lidar on the car is variable. of

Abstract

The present application provides a parameter monitoring method, device, equipment, and storage medium. The terminal may be an unmanned vehicle, and the method includes: respectively acquiring point cloud data and calibrated parameters of multiple radars calibrated on the terminal ; Based on the calibrated parameters, respectively extract the projection data of the point cloud data of each of the radars in the preset plane; according to the projection data, respectively analyze the difference between two radars among the plurality of radars Change information between and output the change information. This application realizes the real-time parameter monitoring of the multi-line radar installed on the unmanned vehicle, which improves the safety factor of unmanned driving.

Description

technical field [0001] The present application relates to the field of unmanned driving technology, and in particular, to a parameter monitoring method, device, device and storage medium. Background technique [0002] At present, lidar is widely used in the field of autonomous driving, especially many unmanned vehicles are equipped with more than one multi-line lidar. Since the sensor calibration is required before the unmanned vehicle leaves the factory, the specific position of the lidar on the vehicle is already known. Known. [0003] However, during the driving process of the vehicle, it is inevitable that the body will shake, which will easily cause the position of the lidar to change slightly, and the calibration parameters will fail, which will affect the driving state of the vehicle. Therefore, the position of the lidar on the vehicle is variable. of. [0004] In order to ensure the good operation of the unmanned vehicle, there needs to be a method that can detect ...
