A New Method for Airborne Laser Altimetry Points Cloud Patch Segmentation

The method of airborne laser scanning altimetry footprint point cloud patches segmentation is discussed,a new method used to segment the footprint point cloud of group buildings is given,which is called "scanning strip method".The algorithm and flow chart of the method is demonstrated in detail.The practice shows that the algorithm is efficient,reliable,accurate,and can save great time of segmentation as well.
