“…Various investigations (Wenzel et al, 2013;GonizziBarsanti et al, 2014;Toschi et al, 2014;Macher et al, 2017) demonstrated that, with respect to other methods, automation in image-based methods has reached a very efficient level in various application projects, with great potentials. Beside some processing open issues (Nocerino et al, 2014;Menna et al, 2016;Remondino et al, 2017), image acquisition is still a very crucial step, limiting the quality of the final 3D results. Particularly, in case of mass heritage 3D digitization projects (Europeana; Google Art Project; Santos et al, 2017aSantos et al, , 2017b or complex objects with non-collaborative surfaces, the whole 3D digitization pipeline based on a manual image acquisition followed by an offline processing may be not cost effective.…”
