A simple and cheap tool has been developed for measuring shards of old ceramics, found in archaeological yards. It is based on a digital camera, and various photogrammetric and computer vision freeware completed by home-made software developments. The paper presents the equipment used for the acquisition of the images, and the processing software for the various steps. This software is mainly based on algorithms originating from computer vision community, and from more classical photogrammetry. Some intermediate results are presented, the final output of the present work being a very dense cloud of points describing the geometry of the surface of the shard, that may be post processed by many off-the-shelf drawing commercial software, depending on the needs of the archaeologists.
