Paper Abstract

This paper presents one from-Coarse-to-Fine approach to geo-register photogrammetry image sequence to un-textured LIDAR point clouds. First, Photogrammetric Automatic Aerial Triangulation (AAT) Technique is altered to coarsely geo-register image sequence to LIDAR points; After that, LIDAR-Image-Mutual line feature extraction and correspondence strategy is proposed to generate 3D space line from LIDAR points, extract image lines and establish correspondence effectively; Next, "Line Photogrammetric" technique is utilized to map generated conjunctive line features and to refine previous geo-register result under Least Squares adjustment; Finally, geo-registration experiment with developed approach is conducted and contributions are concluded as well. The experimental result shows that proposed approach is robust and effective.
