A method, system, apparatus, article of manufacture, and computer-readable storage medium provide the ability to merge multiple point cloud scans. A first raw scan file and a second raw scan file (each including multiple points) are imported. The scan files are segmented by extracting segments based on geometry in the scene. The segments are filtered. A set of candidate matching feature pairs are acquired by registering features from one scan to features from another scan. The two raw scan files are merged based on the candidate matching feature pairs.
