Research on Point Cloud Registration Error Propagation

Abstract:

According to theory of photogrammetry image matching, registration problems about multistation point clouds are analyzed.Then,error propagation rules are discussed in detail and error propagation model for point clouds registration is established.By experiments,the quantitative relationship between precision of point clouds and model accumulation errors is verified,and which can be used to evaluate registration quality of point clouds.

Key words:terrestrial 3D laser scanning; point cloud registration; registration error; error propagation model
