METHOD OF CALIBRATING A COMPUTERBASED VISION SYSTEM ONBOARD A SELFDIRECTIONAL MOBILE PROBLEM The Localization task is a critical stage for an automatic guidance device in a vehicle used for transport of people or merchandise. This task needs an accuracy that is on the order of the ten centimeters. Classical devises used in this field are centrimetric GPS or whether guided wave systems or LASER guided. PATENT WO2013053701 FR2981185 US14/350983 JP Number in stand by AU Number in stand by CA Number in stand by EP 12769446.1 INVENTORS Dhome Michel, Royer Eric, Lhuilier Maxime, Ramadasan Datta, Karam Nadir, Deymier Clement, Litvinov Vadim, Hadj Abdelkader Hicham, Chateau Thierry, Lavest Jean-Marc, Marmoiton Francois, Alizon Serge, Malaterre Laurent, Lebraly Pierre LABORATORY Institut Pascal Team: ComSee VISIT US: TECHNOLOGY DESCRIPTION The present invention relates to a system of vision with computer embarked on a mobile. The invention allows a rebuilding 3D of an environment, a 3D re localization, and finally the guidance of a self-directional mobile. One of the goals of the invention is to provide a process of calibration, making it possible to estimate with precision the extrinsic parameters and/or the intrinsic parameters of the whole of cameras, which is fast to implement. With this effect, the invention proposes a process of calibration of a system of vision per computer embarked on a mobile, a product and a device. APPLICATIONS Autonomous vehicle for the transport of people, Autonomous vehicle for the transport of merchandize Self-directional robots All application based on localization technologies CURRENT STAGE OF DEVELOPMENT License Maturation in progress OPPORTUNITY: Look for collaborative research CONTACT : Business developper – Jean-Sébastien Guez - [email protected] © 2014 – Université Blaise Pascal AVAILABLE FOR COLLABORATIVE RESEARCH However, guided wave systems need marking modifications and so the infrastructure. The centrimetric GPS has major disadvantage, in fact it is not available in an urban environment with large buildings. Moreover it is not available in the indoor environment.
