A camcorder for 3D underwater reconstruction of archeological objects

The underwater cartography has made great progress in the last decade. In this paper, we discuss of the 3D underwater cartography problem and propose a multimodal fusion approach. The work presented in this paper is about the analyze and 3D reconstruction of archeological objects. Using an uncalibrated single camera, we propose to describe a method with enables first, to calibrate this camera integrating variation of the water optical refractive index to the distortion model. And secondly, robust and stable features have been extracted. A comparison of two methods of detecting and matching points is presented. Finally, we estimate the movement between different images and compare two methods.
