Camera calibration experiment based on Harris algorithm
The camera calibration is a hot issue in the field of photogrammetry. A chessboard plane is introduced to simplify the difficulty of calibration. In this paper, first, corners of chessboard are detected by Harris. Then, geometrical relationships are calculated between image plane and the three-dimensional space. Finally, the intrinsic and external parameters of the camera are calibrated based on camera model. Experimental results show that the method is effective.
