In this paper we propose an extrinsic calibration method of regular camera and single line scanning li-dar which are widely utilized together. Based on a long ignored aspect that infra-red (IR) source for commonly used lidars lies in the response range of regular cameras, we employ an auxiliary IR filter (blocking natural light and letting IR pass) in order for camera to image the scan traces of lidar by prolonging exposure time. Then by scanning V-shaped target such as the intersection of two… CONTINUE READING
