Accurate 3-D reconstruction from trinocular views through integration of improved edge-matching and area-matching techniques

This paper describes a method for obtaining a reliable 3D reconstruction of close-range objects by properly combining edge- and area-based matching techniques. The adopted acquisition system is a set of three calibrated low-cost CCD cameras. By using an accurate camera model and camera calibration, the method is capable of working with any camera setup. The proposed technique has been tested on some real scenes with encouraging results. Some of these experimental results are presented here.
