Abstract

The paper presents a new technique to infer 3D information using a static camera provided with a zoom lens. The modelling process is straightforward and does not involve the computation of intrinsic camera parameters. The approach is based on the exploitation of images of accurate regular grids. The main idea is to compute a transformation which allows to obtain a relationship between the real grids (without distortion) located in front of the camera and their distorted images on the CCD matrix. This relationship takes automatically all the distortion phenomena into account. Previous work in reconstruction by zooming involved high quality optical systems. The principal aim of the present work is to generalize this kind of reconstruction in the case of a standard zoom lens
