In passive binocular stereovision, there are generally two approaches: the lateral stereovision and the axial stereovision. The authors present a study relating more particularly to axial stereovision. Most of the works on axial stereovision have been theoretical. These studies have not been followed by real experiments because their authors could not produce a practical description of an axial stereovision system. The present authors propose a method to get a real axial stereovision system by calibration then by rectification. They also compare their axial stereovision system calibration method to the only one serious calibration process they found in the existing papers

It is shown that it is possible to infer 3-D information from a set of images taken with a zoom lens. A precise study of the optical properties of such a lens gives two major results: The intersection between the optical axis and the image plane can be independently and accurately determined, and the pin-hole model cannot be used directly for the approximation of such a complex lens system. To explain the optical phenomena occurring during a zoom-lens focal-length change, it is shown that a thick optical model must be considered. Experimental reconstruction results for a set of real images, are given
