This method could retain the point cloud data which reflects the surface character of object with higher simplification efficiency. The example shows that this method could simplify the scan line point cloud data got by 3D laser scanner directly and effectively. Finally, the angle-chord comprehensive simplification method is prompted. Secondly, the angle deviation error and chord deviation error simplification method is researched based on the analysis of characteristic of 3D laser scan point cloud data. ![]() Firstly, the conventional point cloud data classification and simplification method is introduced. The density of acquired data by 3D laser scanner is huge and is not convenient for curved face reconstruction, model reconstruction, data storage, data display and transmission.
