Patent number: 11854220Abstract: A system and a method for measuring the profile of a part. The measurement system includes a sensor with a probe having at least one degree of freedom, and a first reference element fastened to the probe. The sensor is arranged so that the probe is able to follow the internal or external contour of the part while the first reference element is outside the part. An imaging device is adapted to capture an image representing at least a portion of the outside of the part and the first reference element. Thus, the first reference element serves as a reference element for the position of the probe relative to the reference system that is the part.Type: GrantFiled: November 28, 2019Date of Patent: December 26, 2023Assignee: WATCHOUTCORP SAInventors: Philippe Jacot, Sébastien Laporte, Frédéric Perret

Patent number: 11549801Abstract: A three-dimensional target capable of serving as a positioning reference, including, on a useful face, a first structure and a second structure. The first structure defines a planar reference face divided up between at least a first portion whose surface is reflective according to a diffuse reflection, and a second portion whose surface is reflective according to a specular reflection, the second portion being divided up according to a series of localized zones positioned in the first portion. The second structure has an inclined face relative to the planar reference face. Applicable to three-dimensional optical measurement of the relative position between a first object and a second object.Type: GrantFiled: November 29, 2018Date of Patent: January 10, 2023Assignee: LDI FINANCESInventors: Philippe Jacot, Sebastien Laporte, Frederic Perret

Patent number: 8335674Abstract: A method of producing a finite-element model of a unique body of complex shape having an outer surface that is known in the form of a cloud of points describing said surface analytically or algebraically in a determined frame of reference, the method comprising the steps of a) using a parameterizable and generic finite-element model made up of simple geometrical volumes and representative of the family to which the unique body belongs, b) adapting said model as a function of parameters describing the unique body that is to be modeled; c) in said frame of reference, adjusting the parameterized generic finite-element model and causing the surface nodes of said parameterized model to correspond to points of the known outer surface of the body by projecting said nodes onto said surface along a direction that is normal to the surface of the generic model, and d) using the nodes of the surface as control points for a three-dimensional interpolation method in order to personalize the internal finite elements of theType: GrantFiled: May 11, 2007Date of Patent: December 18, 2012Assignee: Societe d'Etudes et de Recherches de l'Ecole Nationale Superieure d'Arts et Metiers (Seram)Inventors: Laure Duchemin, Sébastien Laporte, David Mitton, Wafa Skalli

Patent number: 7639866Abstract: A radiographic imaging method for three-dimensional reconstruction in which the three-dimensional shape of a model representing an object is calculated from a geometrical model of the object that is known a priori, and obtained from a confinement volume of the object estimated from a geometrical pattern visible in two images and from knowledge of the positions of the sources. A geometrical model is used that comprises information making it possible using an estimator for the object to establish a geometrical characteristic for the model representing the object.Type: GrantFiled: December 22, 2003Date of Patent: December 29, 2009Assignee: Biospace MedInventors: Vincent Pomero, Wafa Skalli, Sylvain Deschenes, Jacques de Guise, Sébastien LaPorte, Benoit Godbout, Dominic Branchaud, André Bleau, David Mitton, Irène Dorion
