摘要：Terrestrial laser scanning is a recognised technique for the geometric documentation of objects and surfaces in a variety of applications but the amount of information acquired by laser scanners makes the registration of pairs and multiple scans a complex problem. Thus, the general scanning practice still requires the use of signalised targets placed at selected locations on the surface of the scanned object. In this paper a methodology for point cloud registration via image-based information and without the use of targets is presented. For this purpose, a specific number of control points located on the object surface are used. These points are identified automatically on photographic images taken during laser scanner data acquisition from an external high resolution CCD camera mounted on the scanner device. Following the presentation of the method, the application on the documentation of a cultural heritage building is described
