a fully automatic approach for reconstructing road surface features based on the terrestrial mobile light detection and ranging (lidar) technique ![[27a36d0e1f4f46f2a4d43b4ab00a7a2.png]]

road surface extraction： 就是filter路面出来 candidate object identification： transformed into 2D regular grid images> 去噪音（Morphological image processing）> cluster（Component labeling） feature classification quality evaluation
