Facilitating environment Reconstruction based on Stereo Camera using calibration information

Simplification and automation of the process of visual and geometric reconstruction is one of the issues considered in 3D modeling of environment, especially in urban areas. A stereo camera, as the positions of its lenses are fixed relative to each other, can be used to facilitate the modeling process. This article shows that using stereo camera calibration data, producing 3D environment model can be facilitaded without needing for matching process, especially in the areas that the matching has problem because of unsufficient information need for it. Moreover, using camera calibration information, geometric information and depth map of the environment can be extracted and produced without the need to define the specified scale between features. In the following, the results of investigations carried out for the reconstruction of urban environment are expressed.
