Abstract. 3D high resolution models can be produced both using range-based and image-based techniques. In this work, we evaluate the performance of the Photoscan commercial software in a challenging project: the digitization of an earthenware frieze of about 36 m in length. In order to choose the most effective technique and to define the best workflow for on-the-field data acquisition and the subsequent data elaboration, some tests were performed on a portion of the frieze. We discuss the results and compare the models resulting from different workflows with a reference data set taken from the scan data.
