Abstract:

This paper proposes a method for rapid and continuous monitoring of slope deformation by using terrestrial optical photogrammetry. This slope monitoring method is non-contact and has a high speed to calculate the position and displacement of slope points, which can be applied to the continuous observation and disaster warning of the problem area of the slope. The theory of this method is to obtain the sequence image of the slope through the ground observation platform, and then use the SURF algorithm to generate the 2D displacement field in image plane, and finally orthorectify by using the DTM to calculate the displacement of the slope points. When the displacement of slope point exceeds the threshold, it can be considered that the corresponding position may be unstable and will occur slope sliding.
