Software for camera calibration and 3D points reconstruction in stereophotogrammetry

This paper deals with the problem of a camera calibration for a photogrammetry and computer vision purposes. Mathematic formulation of the 3D point representation in an external space and its transformation into 2D image space is exposed. The pinhole camera model is used for a problem simplification The camera calibration problem represents intrinsic and extrinsic parameters determination. The stereo correspondence problem is outlined also. Finally the designed special software (Recon3D) for 3D reconstruction is presented.
