| Abstract: | Briefly describes the technical characteristics of rotating multi-baseline digital close-range photogrammetry system and a specific implementation plan in this paper,and proposed a no secondary control,non-contact,fast and convenient for landslide monitoring method based on rotating multi-baseline Intersect the direction of photography.By describing key processes for landslide monitoring and field test,we can analyzed the impact of different photo station number,the base-height ratio and the contact angle on the accucacy.The experiment proved the feasibility of the method and the accuracy can reach a millimeter. |
