The placement angle parameters have a significant impact on the accuracy and quality of point cloud data in airborne LiDAR operations,causing changes in the true position of ground objects and layering of adjacent aerial point clouds.Howev-er,the traditional calibration mode of deploying ground control points has low efficiency,high cost,high requirements,and poor operability.To avoid the aforementioned drawbacks,a placement angle adaptive calibration model is proposed,by itera-tively matching the spatial positions of a large number of identical feature points within adjacent overlapping airstrips and calcu-lating the placement angle parameters,the least squares configuration method is used to solve the three placement angle param-eters of the airborne LiDAR scanning system.The algorithm program is implemented using C language,which has been veri-fied in test cases,improving the efficiency of placement angle calibration and improving the processing quality,applicability and operability of point clouds in complex terrain using airborne LiDAR technology.
