A 3D survey in archaeology. Comparison among software for image and range-based data integration

This paper aims to evaluate the performance, in terms of accuracy and speed, of various commercial software (Reality Capture©, Agisoft Metashape© and 3DF Zephyr©) for integration among image and range-based survey data. Datasets were collected in the Nuragic complex called "la Prisgiona" (Arzachena, SS, Italy), during a collaborative research project between CNR-ISPC and the Municipality of Arzachena, using aerial photogrammetry, topographic and TLS survey. Results of comparative tests demonstrate that, when working on architectural scale survey, passive and active techniques are to be considered homologous in terms of accuracy and precision.
