Error Evaluation in a Stereovision-Based 3D Reconstruction System
Autor: Abdelkrim Belhaoua, Sophie Kohler, Ernest Hirsch
Publikováno v: EURASIP Journal on Image and Video Processing, Vol 2010 (2010)
The work presented in this paper deals with the performance analysis of the whole 3D reconstruction process of imaged objects, specifically of the set of geometric primitives describing their outline and extracted from a pair of images knowing their

A comparative study of multi-sensor data fusion methods for highly accurate assessment of manufactured parts
Autor: Ammar Hannachi, Ernest Hirsch, Alex Lallement, Sophie Kohler
Publikováno v: Twelfth International Conference on Quality Control by Artificial Vision 2015.
3D modeling of scene contents takes an increasing importance for many computer vision based applications. In particular, industrial applications of computer vision require efficient tools for the computation of this 3D information. Routinely, stereo-

Multi-sensor data fusion for realistic and accurate 3d reconstruction
Autor: Sophie Kohler, Ammar Hannachi, Alex Lallement, Ernest Hirsch
Publikováno v: EUVIP
In this paper, the problem of multi-sensor data fusion for 3D dimensional reconstruction/assessment of manufactured parts is investigated. For this, a method relying on cooperation of two acquisition/processing techniques (stereoscopic and structured

From the Hough Transform to a New Approach for the Detection and Approximation of Elliptical Arcs
Autor: Pierre Graebling, Ernest Hirsch, Christian Daul
Publikováno v: Computer Vision and Image Understanding. 72:215-236
The edges of simple geometrical (e.g., manufactured) parts can generally be approximated sufficiently accurately by straight-line segments and elliptical arcs in order, for example, to carry out a dimensional analysis of these parts, such as required

Illumination control in view of dynamic (re)planning of 3D reconstruction tasks
Autor: Abdelkrim Belhaoua, Ernest Hirsch, Sophie Kohler
Publikováno v: SPIE Proceedings.
Accuracy of 3D vision-based reconstruction tasks depends both on the complexity of analyzed objects and on good viewing / illumination conditions, ensuring image quality and minimizing consequently measurement errors after processing of acquired imag

Estimation of 3D reconstruction errors in a stereo-vision system
Autor: S. Kohler, Ernest Hirsch, A. Belhaoua
Publikováno v: Modeling Aspects in Optical Metrology II.
The paper presents an approach for error estimation for the various steps of an automated 3D vision-based reconstruction procedure of manufactured workpieces. The process is based on a priori planning of the task and built around a cognitive intellig

Significance of crystal growth of proteins and nucleic acids in biology: Novel ways in crystallogenesis
Autor: Richard Giegé, Jean-Luc Rodeau, Vincent Mikol, Ernest Hirsch
Publikováno v: Journal of Crystal Growth. 99:1017-1022
Until recently crystallization of macromolecules was rather empirical. Stimulated by developments of biotechnology and by the crystallization programs under microgravity, this empirical field is moving towards the new discipline of biological crystal
