Filtering of Airborne LiDAR Point Cloud Based on Variable Radius Circle and B-spline Fitting

Filtering is the key to acquire digital terrain model from airborne LiDAR point cloud. In this paper, a new LiDAR point cloud filtering method is proposed. First, the scanning lines formed with point sequence are obtained throuth scanning the point cloud along the same direction. Then a circle with...
