Embodiment Construction
[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0015] According to one or more embodiments, a method for dynamic calibration of roadside sensors is disclosed, such as figure 1 mentioned, including the following steps:
[0016] S1. Receive the raw data collected by each sensor, including camera image data obtained through the camera, the laser radar point cloud obtained through the laser radar, the millimeter wave radar point cloud obtained through the 4D millimeter wave radar collection, and the integrated navigation. Combined navigation information.
[0017] Among them, the integrated navigation needs to be installed on the calibration target and fixedly connected with the calibration target. For data collection by cameras, lidars, and 4D millimeter-wave radars, it is necessary to calibrate the target and collect data when the positioning signal is judged to be good according to the set standards and m...
