Paper Abstract

The 3D reconstruction of a scene with 2D images requires several scene acquisitions or the use of specific lighting (structured light). The solution choice depends on the scene to be reconstructed. Unfortunately in the case of face reconstruction, health standards forbid the use of structured light; the elaboration of a multi-sensor system, such as stereovision is then required. In this paper, primary results about depth reconstruction from defocused images are presented. The used method relies on inverse ray tracing and provides results better than those obtained by using the conventional gradient based method.
