Abstract

Photogrammetry is a non-invasive technique that is acquiring major importance for documentation and construction of 3D models. Nowadays, many 3D models are created and shared, with only few information about the trustworthiness of the final model. In general, it is possible to have only basic statistical information and quality descriptors related to the software processes. Therefore, the authors propose a novel approach that trough the use of a standard object within the acquisition scene allows one to check to overall quality of a model with trustworthy metric information. Archiving and sharing 3D models, even if nowadays thanks to many commercial and open source software is an easy task, could be a tricky procedure. Indeed, a model could be a photorealistic reproduction and at the same time it could carry wrong metric information. In the field of cultural heritage, in which photogrammetry is a technique applied for documentation, monitoring, dissertation and archiving, sharing incorrect data should be an avoided practice. This paper presents the developing of a specific 3D standard for the photogrammetry process characterization and discusses the new experimental approach proposed.
