Abstract

In order to fuse heterogeneous data with high precision, then express the buildings roof and facade information fully, this paper proposed a registration method of terrain laser scanning point cloud and image matching point cloud based on buil-ding footprint features. It extracted image matching point cloud building roof edge by boundary estimation, got terrain laser scanning point cloud building eaves boundary by α-shape algorithm, completed two footprint point cloud's coarse registration by principal component analysis algorithm, centroid constraint and Rodrigues's formula, finished fine registration according to the ICP algorithm. Experimental results show that the method can combine the advantages of cross-modal data, and improve the calculation efficiency and registration accuracy of image and point cloud registration effectively.
