A method for finding analytical solutions to the problem of determining the attitude of a 3D
object in space from a single perspective image is presented. Its principle is based on the …

Given a perspective projection of line segments on the image plane, the constraints on their
3D positions and orientations are derived on the assumption that their true lengths or the …

This paper presents a new method for three-dimensional camera calibration in which the
rotation parameters are decoupled from the translation parameters. First, the rotation …

Since the last years, we are interested in visual servo-ing and we ha ve dev eloped many
visual servoing applications using 2D visual features. The aim of this paper is to study how …

This paper introduces a new relation, called the perspective angle transform (PAT), to deal
with shape-from-angle problems, together with its application to 3D configuration recovery …

A general procedure for the understanding of a class of indoor scenes is proposed. The
suggested algorithm makes use of an extensive 2-D processing of the image that provides a …

Applications of automated planning under uncertainty are often modelled as a discrete and
continuous state Markov Decision Process (DC-MDP). Symbolic Dynamic Programming is …

This paper deals with motion estimation from image corner correspondences in two cases:
the orthogonal corner and the general corner with known space angles. The contribution of …

A method to find the analytical solutions of the inverse perspective problem for the
determination of the 3-D object attitude in space from a single perspective image is …

This paper presents a new method that permits to estimate, in the viewer coordinate system,
the spatial attitude of an articulated object from a single perspective image. Its principle is …
