Description:
Current 3D acquisition technologies can deliver highly accurate data on the shape of real-world objects. Despite the recent advances in the field of geometry processing and 3D reconstruction, producing complete and defect-free multi-scale geometric models of objects that are as complex as pieces of artwork or buildings still cannot be achieved in a full automatic way, which hampers massive scanning campaigns. Standard 3d reconstruction techniques often require a large amount of user interaction to adjust parameters or to perform corrections, which essentially rely on some visual criteria. The recent advances of 2D/3D registration techniques open up new lines of research to bring solutions to the problem of automatically reconstructing complete and multi-scale accurate 3D models with few constraints on the acquisition process.

The goal of this thesis is to develop a technique that takes benefit from the information obtained from a set of photographs to evaluate and improve the reconstruction of 3D models from 3D scans. This technique will be based on a novel metric that allows to compare a calibrated set of photographs to a set of 3D scans. This technique will be studied in conjunction with a representation making it possible to visualize complex reconstructed models in real-time. The implementation will be achieved in C++ and it will be incorporated into the digitization software of the IGG group.
