Traffic Monitoring Research Based on Roadside LiDAR-Camera Target-free Wide-area Collaborative Calibration

Accurate external parameter calibration of roadside lidar and camera is the key premise to realize multi-sensor data fusion and accurate perception of traffic targets. The traditional method based on calibration board needs manual intervention and will cause traffic interruption, which is difficult to meet the deployment and operation and maintenance requirements of large-scale roadside sensing system. In this paper, a lidar camera wide domain collaborative calibration method for roadside traffic monitoring scene is proposed.
