Patent number: 10643343Abstract: A method for matching points between three images of a scene comprises retrieving three images acquired by a sensor, extracting blobs from said reflection in said two images; for each given extracted blob of the first image: selecting a selected epipolar plane; identifying plausible combinations; calculating a matching error; repeating the steps of selecting, identifying and calculating for each epipolar plane of the set of epipolar planes; determining a most probable combination; identifying matching points between the two images; validating the matching points between the two images, said validating comprising for each pair of matching points, determining a projection of the pair of matching points in a third image of the third camera; and providing the validated pairs of matching points.Type: GrantFiled: April 11, 2019Date of Patent: May 5, 2020Assignee: Creaform Inc.Inventors: Félix Rochette, Patrick Hébert, Olivier Gignac, Martin Soucy, Antoine Thomas Caron

Patent number: 10271039Abstract: A method for matching points between two images of a scene acquired by two cameras, the method including: extracting blobs from the reflection in the images and individually labelling the blobs with a unique identifier; selecting a selected epipolar plane and defining a conjugate epipolar line on each of the images; identifying plausible combinations including a light sheet label of the projected pattern and the unique identifier for a plausible blob selected from the blobs in each of the images; calculating a matching error for each of the plausible combinations; repeating the steps of selecting, identifying and calculating for at least some epipolar planes; determining a most probable combination by computing a figure of merit for the plausible combinations; identifying matching points in the frame from the most probable combination.Type: GrantFiled: February 4, 2015Date of Patent: April 23, 2019Assignee: Creaform Inc.Inventors: Dragan Tubic, Martin Soucy, Olivier Gignac, Antoine Thomas Caron

Patent number: 9194853Abstract: The invention concerns the use of cyclic azaboronates as sensitive materials in sensors for the detection of the presence of peroxides, in particular hydrogen peroxide, in a gaseous environment. It further concerns new cyclic azaboronates, as well as sensors comprising these azaboronates as sensitive materials. Applications for the invention include the following: fight against terrorism, monitoring for security purposes of sites in which peroxides or peroxidable compounds are manufactured, stored, and/or used, monitoring of atmospheric pollution, etc.Type: GrantFiled: October 17, 2011Date of Patent: November 24, 2015Assignee: COMMISSARIAT A L'ENERGIE ATOMIQUE ET AUX ENERGIES ALTERNATIVESInventors: Thomas Caron, Myriam Bouhadid, Eric Pasquinet, Pierre Montmeat, Francoise Serein-Spirau
