Summary: | The invention provides a sludge discharge reservoir geotechnical cloth point cloud extraction method. The method comprises the following steps: S1, acquiring three-dimensional color point cloud data of a sludge discharge reservoir area; s2, carrying out histogram normalization processing on the point cloud data, and recording the processed point cloud data as OriginPt; s3, carrying out preliminary screening on the OriginPt according to the color information, and recording the screened point cloud data as WhitePt; s4, performing histogram statistics on the WhitePt according to the elevation Z value to obtain an elevation interval of the geotechnical cloth; step S5, using color information and an elevation interval as threshold conditions, performing secondary screening on the OriginPt, and recording the screened point cloud data as SelectedPt; and step S6, carrying out de-noising processing on the SelectedPt to obtain a geotechnical distribution point cloud. The problem of accurate extraction of the three-dime |
