Development and application of point cloud profile analysis system for measuring reservoir sedimentation measurement
To rapidly compare and analyze point cloud profile characteristics of reservoir sediment accumulation measurements from different periods and to promptly understand the sedimentation status in various reservoir areas thus enhancing the efficiency of profile analysis,a reservoir sediment accumulation point cloud profile analysis system was developed and implemented.By reading underwater three-dimensional point cloud data of the reservoir from different periods in a three-dimensional visualization context and through interactive operations picking two-point coordinates of the point cloud corresponding region,a vertical profile is generated.The system calculates the distance from all point cloud data to the profile,selects all points whose distance does not exceed a predetermined threshold,projects them onto the profile,and fits the profile lines from different periods for comparative analysis.With the reservoir sediment measurement data of a concrete gravity dam in southwestern China as support,the application results demonstrate that the research outcomes provide a simple and fast technological means for analyzing the degree of sediment accumulation in reservoirs at different periods,enhancing the intelligence level and efficiency of reservoir sedimentation analysis.
