According to the terrain features of the tailings dam, the water boundary image of the tailings dam is obtained by the acquisition of the water. The contour recognition, threshold segmentation, and watershed algorithm can be used to retrieve the boundary between dry beaches and water surface. Analyze and deal with the image pixel coordinates, the most accurate pixel coordinates of waterline can be real-time measured. According to the terrain characteristics of tailings pond, through camera monocular visual to calculate the waterline pixel coordinates and the actual length of beach geometric conversion formula, and real-time monitoring of dry beach length. Based on monocular vision with the fixed dry beach slope, the algorithm is proved to meet the requirements of dry beach length measurement.
