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 invention provides a parameter monitoring method and device, equipment and a storage medium; a terminal can be an unmanned vehicle, and the method comprises the steps of respectively obtaining thepoint cloud data and calibrated parameters of a plurality of radars calibrated on the terminal; based on the calibrated parameters, respectively extracting projection data of the point cloud data ofeach radar in a preset plane; and according to the projection data, analyzing change information between every two radars in the plurality of radars, and outputting the change information. According to the invention, real-time parameter monitoring of the multi-line radar installed on the unmanned vehicle is realized, and the safety coefficient of unmanned driving is improved.

Description

technical field [0001] The present application relates to the technical field of unmanned driving, in particular, to a parameter monitoring method, device, equipment and storage medium. Background technique [0002] At present, lidar is widely used in the field of autonomous driving, especially since more than one multi-line lidar is installed on many unmanned vehicles. Since the sensor calibration needs to be performed before the unmanned vehicle leaves the factory, the specific position of the lidar on the vehicle is determined. Known. [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. [0004] In order to ensure the good running status of unmanned vehicles, there needs to be a method to detect whether the ex...
