Abstract
Camera calibration and images rectification are two necessary steps in most 3D reconstruction methods using
image acquisition. This paper proposes an evaluation procedure for camera calibration methods for the case of
3D reconstruction using rectified multi-stereo images. The evaluation is based on the accuracy of the rectification
and of the 3D reconstruction which are directly related to the calibration precision. Three methods are thus
compared: Faugeras-Toscani, Zhang and a robust calibration algorithm. The procedure can be applied for
computer vision systems with an arbitrary number of cameras and for any other calibration method. We show
that, although the three methods provide significantly different intrinsic and stereo system parameter estimations,
the rectified images of the planar target that we use for evaluation are relatively coherent and lead to close 3D
reconstruction errors.
