Patent number: 11631221Abstract: A computer-implemented method of augmented reality includes capturing the video flux with a video camera, extracting, from the video flux, one or more 2D images each representing the real object, and obtaining a 3D model representing the real object. The method also includes determining a pose of the 3D model relative to the video flux, among candidate poses. The determining rewards a mutual information, for at least one 2D image and for each given candidate pose, which represents a mutual dependence between a virtual 2D rendering and the at least one 2D image. The method also includes augmenting the video flux based on the pose. This forms an improved solution of augmented reality for augmenting a video flux of a real scene including a real object.Type: GrantFiled: December 30, 2020Date of Patent: April 18, 2023Assignee: DASSAULT SYSTEMESInventors: Eloi Mehr, Vincent Guitteny

Patent number: 9886530Abstract: The invention notably relates to a computer-implemented method for designing a 3D modeled object representing a real object. The method comprises the steps of providing a 3D representation of the real object, identifying occurrences of a geometric feature at 3D positions of the 3D representation, providing at least one 2D view of the real object, identifying occurrences of a graphic feature at 2D positions of the 2D view, the geometric feature corresponding to the graphic feature, computing camera parameters that minimize a distance between a set of projections of the 3D positions on the 2D view and a set of 2D positions. This provides an improved solution for designing a 3D modeled object representing a real object.Type: GrantFiled: November 14, 2014Date of Patent: February 6, 2018Assignee: Dassault SystemsInventors: Eloi Mehr, Vincent Guitteny, Mourad Boufarguine
