Abstract
This paper proposes a novel object segmentation method for 3D Light Detection and Ranging (LIDAR) data that is particularly useful for the traffic scene analysis of self-driving vehicles. The novel method gains robustness against under-segmentation, i.e. The problem of assigning several objects to one segment, by jointly using geometrical features and motion field information to discriminate even spatially close objects in the data. The approach maps point cloud data to an occupancy grid representation and estimates the motion field using Kalman filter based tracking of grid cells. A non-parametric Bayesian clustering approach based on a sequential distance dependent Chinese Restaurant Process (s-ddCRP) utilizes this information in order to sample possible data segmentation hypotheses and decide on the most probable one.
