| Abstract: | These authors take the scene photographs of Guangdong Grand Canyon with close-range photogrammetry technology,and obtain digital information of the Grand Canyon with control points which are set up on the work field fast accurately.Finally,these authors get the points cloud,elevations etc.and analyze the direction error of control points and the plane and depth accuracy.The results show that the method is effective and feasible high precision,and provide a reliable basis for decision makers,meanwhile,verify... |
