Paper Abstract

In the last decade, the demand of 3D models for objects documentation and visualization is drastically increased. 3D modeling of close-range objects is required in different applications, like cultural heritage, industry, animation or medicine. While Photogrammetry is a well proved technique for 3D reconstruction of real objects, featuring important properties like accurate sensor calibration, use of both analog or digital imageries, low cost and high portable system, laser scanning technology is becoming a very promising alternative for surveying and modeling applications. Tipically, laser scanners allow for fast acquisition of huge amount of 3D data which can be often combined with colour hi-res digital images. As a result, real objects can be represented with a higher level of detail together with a good metric accuracy. Among several works so far presented about laser scanning for cultural heritage survey, some modeling and accuracy related issues have been not yet solved and discussed in details. In this contribution we report about two case studies realized with photogrammetry and laser scanner and we provide some advices and suggestions about the more suitable 3D modeling method for a given object, taking into account its size and shape complexity, the required accuracy and the target application.
