| Descripción |
We present an ellipse-based camera calibration. Correct measures in the image are required to perform the camera model estimation. We suggest a technique, based upon surface photometry, allowing to compute robustly and accurately the moments of a shape in an image, and use them as inputs for the estimation algorithm. Connections between the specification of a 3D-ellipse, the moments of its image and calibration parameters are described. These equations are partially extended to models including distortions. Then, the parameters estimation is a non linear problem solved by an iterative algorithm. Tests with synthetic and real images are described and discussed for different camera models.
