software

This software contains several ROS (http://www.ros.org/) (Robot Operating System) modules for processing data from Velodyne 3D LiDAR, e.g. for road and obstacle detection. One of the modules implements a new pipeline for calibration, i.e. mutual pose and orientation estimation, of the camera and LiDAR sensor using a coarse to fine approach. The calibration benefits from a novel 3D marker which can be robustly detected in both the camera image and the LiDAR scan. The method requires only a single pair of camera-LiDAR frames for estimating large sensors displacement. Consequent refinement step searches for more accurate calibration in a small subspace of calibration parameters.
