Abstract	One of the commonest problems in the conservation of big and heavy fragmented objects is the estimation of the original relative position of the fragments (known as the matching problem). Help on the matching problem is obtained using specialized software for the estimation of the original position of every fragment Prior to this the geometry of the fragments must be stored on the computer We consider two non-contact capturing methods: laser scanning and digital close range photogrammetry. Laser scanning has been found to be rapid in use producing a dense, irregular point cloud that describes the object, stored in a digital file. Close range photogrammetry is slower, resulting in sparse measurements on a much more regular pattern Data is stored on film first, and then converted to a digital file. We show how this intermediate step offers advantages related to the potential for future refinement of the model We suggest the combined use of laser scanning for quick and easily usable models together with photogrammetry for future reference records.
