Abstract
The Structure From Motion (SFM) algorithms derived from Computer Vision community make image-based techniquesa competitive and user friendly approach to obtain 3D information of real objects. These algorithms have been implemented in many 3D web-service and open source softwareto develop free instruments for the reconstruction of very detailed 3D digital models. Their useare becoming very common above all in archaeological studies but their potentiality for metric application have not been tested at all.The aim of the work is to investigate the quality and the accuracy of 3D models obtained through 3D web-service and SFM open source software.Different tests have been performed using some 3D web-services (Autodesk 123D Catch, ARC3D, My3Dscanner) and one open source software (VisualSFM). The 3D modelshave been evaluated in comparison with reference models obtained by photogrammetric and laser scanning techniques. The work has showed that in some situations these instrumentscould substitute photogrammetric and laser scanning techniques.
