Photogrammetric Model of Computer Vision |

Abstract: |
The photogrammetric model of computer vision is the fundamental for traffic accident sence measurement system. According to the basic relationship between the spatial points and their image points, the photogrammetric model for camera calibration and sence measurement is built. A linear model is also developed in which the symmetrical lense distortion has been considered. The theoretical and calibration accuracy is analyzed through the experiments. |
