An important task in most 3D vision systems is camera modeling . We present a calibration method designed for a good accuracy in the parameters estimation . Accurate image measurments are required to perform the camera model estimation. We suggest a technique, based upon surface photometry analysis, to compute robustly and accurately the moments of a shape in an image, and use them as inputs for the estimation algorithm. As a consequences, an ellipse-based camera calibration is introduced, which uses the relationships between the specification of a 3D-ellipse, the moments of its image and the calibration parameters . These equations are partially extended to models including distortions .En vision par ordinateur, il est souvent util...
