Abstract
A method for detecting and autonomously tracking a target object using a LIDAR sensor that continuously emits laser pulses onto the target object and generates a 3-D point cloud from measurement points reflected by the target objects at predetermined time intervals. A current relative position of the target object is calculated for six degrees of freedom of movement of the target object at the predetermined time intervals based on algorithms estimating the position. The method includes acquiring a high-resolution initializing point cloud over a plurality of predetermined time intervals, generating a reference model with a small number of measurement points from the initializing point cloud, and, in subsequent iterative steps, determining temporal position clouds and comparing the position clouds with the reference model using the algorithms. Position information of the target object is calculated, wherein the reference model is continuously adapted to the changes in the point clouds.
