Cover Story: The detailed recording of tangible heritage is causally related to the ever-present needs for protection, conservation, and valorization. However, recording technologies change rapidly and allow increasingly higher automation, processing velocities, accuracy, and visual fidelity. Therefore, being up to date with the—continuously evolving—technologies for three-dimensional digitization is crucial to ensure the high quality of heritage documentation. This work offers an updated critical evaluation of imaging and scanning sensors, common capturing scenarios, and processing techniques for heritage objects’ digitization by comparing the quality of metric results. It considers a variety of photogrammetric software, as well as case studies of different geometrical characteristics, to present comprehensive conclusions. View this paper
