Establish A 3-D Model Using Laser Scanner At A Fixed Station

Abstract

To establish a 3-D model without moving laser scanner has been the primary motivation of this study. Compared with traditional ground surveying instruments, laser scanner can be used to collect object’s spatial information in an efficient way. However, when using a laser scanner, it still needs multi-viewpoint way to establish the 3-D model completely. In general, the laser scanner has to be set up at more than two stations, and the data scanned by different viewpoint should be joined together to complete the scan work.\r\nOn the other hand, assume that an object can be rotated, its different part can be scanned using a laser scanner set up only one time. The scanned data can be joined together and generated a 3-D model of the object by using three dimensional conformal coordinate transformations. The whole procedure will be explained in this paper. Results generated from scanning at only one station will also be compared and analyzed.
