摘要：Registration of point clouds in the same coordinate system is the most important step in processing of terrestrial laser scanner measurements. Used methods for registration of point clouds have required scanned overlap area betweeen point clouds or adequate points for every scan in common coordinate system. These procedures are required time and labor more than necessary. In this study, a method has been explained for registration of point clouds in the same coordinate system by one image, which covers the scan area of each point clouds. Essentially, the method is performed in two steps. The first step for the process is calculated the exterior orientation (rotation angles and translation components) of each point clouds with respect to image coordinate system, and image and each scan axes is maked parallel for the other. Translation vector is determined by difference of projection center coordinates in each scan coordinate system. Evaluate of accuracy of the method used here is done by beforhand selected control points coordinates. Seen in the procedure, the method can be used for registration of laser scanner data but accuracy of registration of the method has yet sufficiently. The accuracies of the registration can be increased with removed distortion and other errors.
