| Abstract: | Given the source of the instrumental error of TLS point cloud data and the specific difficulties in modifying it, a method including coordinates transformation is presented. Based on a certain amount of known points' coodinates, a set of measured point cloud data is modified using this method, analysis and discussion of the result are also given. |
