A New Solution to the Relative Orientation Problem Using Only 3 Points and the Vertical Direction
TLDR
This paper presents a new method to solve the relative pose between two images, using three pairs of homologous points and the knowledge of the vertical direction. Expand

PRECISE, AUTOMATIC AND FAST METHOD FOR VANISHING POINT DETECTION
A new automated approach for vanishing point detection in images of urban scenes is described. This method is based on the theorem of Thales. The main contribution of this paper is the automatic andExpand

The Five Points Pose Problem : A New and Accurate Solution Adapted to any Geometric Configuration
TLDR
The goal of this paper is to estimate directly the rotation and translation between two stereoscopic images with the help of five homologous points. Expand

ROBUST AND AUTOMATIC VANISHING POINTS DETECTION WITH THEIR UNCERTAINTIES FROM A SINGLE UNCALIBRATED IMAGE, BY PLANES EXTRACTION ON THE UNIT SPHERE
TLDR
We propose a simple and robust geometry embedded into a larger frame of image work starting with an efficient vanishing point extraction without any prior information about the scene and any knowledge of intrinsic parameters of the optics used. Expand

IMPLEMENTATION OF A LOW-COST PHOTOGRAMMETRIC METHODOLOGY FOR 3D MODELLING OF CERAMIC FRAGMENTS
A simple and cheap tool has been developed for measuring shards of old ceramics, found in archaeological yards. It is based on a digital camera, and various photogrammetric and computer visionExpand

Détection automatique des points de fuite et calcul de leur incertitude à l'aide de la géomét rie projective Automatic detection of vanishing points and their uncertainty based on projective geometry
An entirely automatic algorithm of detection of van ishing points in images of urban stages is presented. This approach leans on a classic theorem of projective geometry (theorem of Chasles-Steiner),Expand

Direct Solution of the 7 parameters transformation problem
In this paper, we propose a new algorithm to solve the 7 parameters transformation problem. Using Grobner bases techniques and solving polynomial systems, we find, in a direct manner and without theExpand
