GPS dam position movement automatic detection system is the use of modern electronic information technology, communications technology and computer technology to achieve the dam body displacement detection index data real-time, automatic, continuous acquisition, transmission, management, analysis and early warning monitoring technology. In this paper, a method of deformation measurement of dam body based on binocular stereo vision is designed. The method uses binocular stereo vision measurement principle, and combines the image preprocessing, image segmentation, corner detection, stereo matching method to calculate the three-dimensional space coordinates of the feature points set on the dam to obtain the dam deformation information. Simulation results show that the dam deformation measurement method can display the deformation data of the dam in real time, and the visualized output can directly display the dam deformation state.
