Abstract

A complete and practical range image sensor development is presented in this paper: from the mathematical modeling to the shape reconstruction. This scanner aims to be integrated in a larger collaborative project. The nal goal is to provide a framework to allow easy comparisons of ancient wooden items by historians. Motivations and expected results are clearly stated in accordance to nancial and easy-to-use constraints. In order to alleviate the calibration process a new calibrating pattern is proposed. The pattern allow both calibration of camera and projector. The method is validated with experimental results. Experimental results are given for the calibration process and the range image acquisition. These results have been performed on both real and synthetic data, which allows us to comment quantitative performances as well as qualitative ones. They are quite encouraging and satisfactory.
