Title: 7 - Estimation récursive de primitives 3D au moyen d'une caméra mobile
Author: RIVES (P.); ESPIAU (B.)
Abstract: On présente un schéma d'estimation de primitives géométriques 3D à partir d'informations continues dans une séquence d'images fournie par une caméra mobile dont le mouvement est connu
Description: This paper presents a scheme allowing to estimate parameters which describe geometrical structures in a 3 D scene by only using informations issued front a sequence of images provided by a mobile vision sensor with known motion . We fisrt recall the basic used models: points and lines, and then we relate their perspective projection in the image plane to the camera motion . Some techniques of recursive filtering are used into the sequence of images to incrementaly build the 3 D scene all along the diplacement of the camera . Some experimental results in the field of robotics are given .
