Remote image coordinate landslide surveillance system and method thereof

The present invention relates to a remote image coordinate landslide surveillance system which comprises: at least one coordinate plane that is set up on a slope to be measured for receiving a set of parallel lights and generating a set of projection point (P2N, P1N); a rotation positioning stage disposed at a remote fixed location. The rotation positioning stage has a base which contains a set of parallel light sources, an acquisition unit and a computation unit. The set of parallel light sources generate a set of projection points on said coordinate plane, the acquisition unit respectively acquires a first images of the projection points (P2N, P1N) at a first time and a second image of the projection points (P2N, P1N) after moving at a second time. The computation unit calculates the changes of coordinates of said projection image (P2N, P1N) and the displaced projection image (P2N, P1N), then determines the landslide situation based on the foregoing changes. The present invention provides a method for remot
