At present, it is difficult to record monitoring data when sluice are opened for flood discharge, especially in the case of dam deformation, the safety will be affected. Therefore, in order to understand the stability state of dam safety, a deformation monitoring system for reservoir dams based on 3D laser scanning is proposed. The working principle and equipment functions of the deformation monitoring system are introduced. The point-to-surface deformation comparison analysis mode is used to monitor dam deformation, and the source program is developed to realize the processing, comparative analysis and modeling of the integrated monitoring point cloud data. The intelligent machine system is applied to the actual monitoring of dam deformation. The results show that the system meets the design requirements in terms of stability, reliability, real-time and accuracy, resulting in higher data integrity rate.
