3D modeling of close-range objects: photogrammetry or laser scanning?

摘要: Photogrammetry has dealt since many years with the 3D reconstruction of objects from images. It provides for accurate sensor calibration and object modeling using analog or digital imageries, it is very portable commercial software available image processing modeling. On other hand, laser scanning technology all related reverse engineering are becoming a promising alternative kind surveying applications. Laser scanners allow to acquire quickly huge amount data which can be often combined color high-resolution Among plenty works so far presented, in particular on use cultural heritage survey, some accuracy issues have been not yet solved discussed details. In this contribution we report about two case studies realized photogrammetry scanner provide advices suggestions more suitable method given object, taking into account its size shape complexity, required target application.
