| Abstract: | The application scope of laser scanning is becoming more and more wide.As a data collecting method,laser scanning technology has been gradually applied in surveying engineering.The basic principle of that and the base used in laser scanning data are introduced in this paper.Besides,3-D rectangle coordinate system used in laser scanning data is transformed to practical coordinate system.While both the accuracy of coordinate transformation model and the impacts on the transformation result caused by other factors are analyzed. |
