Landslide monitoring based on computer vision technology

Landslide is a common geological disaster, which seriously threats people´s safety and property. The landslide monitoring has great significance in reducing landslide loss. This paper aims to design a new method for landslide monitoring with computer vision technology. By this method, mark point should firstly be located in regions where need to be monitored. Then two sets of ordinary digital cameras are used to build stereo vision system, achieve information acquisition in the region of mark points. Finally, the change information before landslides can be achieved through the identification, location, 3D coordinate measurement and displacement judgment on mark points. The experiment results have demonstrated that this method has a high precision in landslide displacement monitoring. It can be used in the real-time landslide monitoring.
