3D documentation and visualization of Cultural Heritage objects is an expanding application area. The selection of the
right technology for these kinds of applications is very important and strictly related to the project requirements, budget
and user's experience. Active sensors, i.e. triangulation based laser scanners and structured light systems are used for
many kinds of 3D object reconstruction tasks and in particular for 3D documentation of cultural heritage objects. This
study presents some experiences in the results of two case studies in which a close-range structured light system is used
for the 3D digitization. The paper includes all necessary steps of the 3D object modeling pipeline from data acquisition
to 3D visualization.
In this paper a work-flow to reconstruct complicated parts of the human body is presented . This approach focuses on the surface measurement of an human shoulder acquired through a synchronized multi image acquisition system. This surface measurement at certain steps of the video sequence will serve as a key frame to fit soft objects related to an articulated skeleton to it and therefore constraint the tracking procedure in the in-between frames. The approach shows a work-flow for a 3D reconstruction of an human shoulder starting with the camera set up and image acquisiton, camera calibration and orientation, and ending in surface measurements and 3D reconstruction of the scene at a certain frame. The calibration and orientation is done with a moving reference field method, making use of the video sequence character. The approximations for the surface measurement procedure are gained through multiphoto cross correlation and the surface measurements and 3D reconstruction are processed with multiphoto geometrically constrained matching. The process is described and tested with synthetic images acquired from a commercial rendering software package. This work is embedded in the REBOMO+ project, which is a joint project with the Computer Graphic Lab of the EPFL Lausanne.
