Abstract

The use of three dimensional computer based models has increased tremendously in the last decades. This is due to the need of numerous emerging applications like telepresence and virtual reality. In the context of telepresence, this paper implements a semi-automatic 3D model reconstruction algorithm from stereo images. The major contribution in this work lies in three main parts: calibration, stereo correspondences, and 3D objects alignement. It is semi-automatic since the calibration technique requires some intervention. However, this will add the ability to change the zoom during the acquisition process.
