Patent number: 11671717Abstract: Embodiments of the disclosure provide systems and methods for motion capture to generate content (e.g., motion pictures, television programming, videos, etc.). An actor or other performing being can have multiple markers on his or her face that are essentially invisible to the human eye, but that can be clearly captured by camera systems of the present disclosure. Embodiments can capture the performance using two different camera systems, each of which can observe the same performance but capture different images of that performance. For instance, a first camera system can capture the performance within a first light wavelength spectrum (e.g., visible light spectrum), and a second camera system can simultaneously capture the performance in a second light wavelength spectrum different from the first spectrum (e.g., invisible light spectrum such as the IR light spectrum). The images captured by the first and second camera systems can be combined to generate content.Type: GrantFiled: May 20, 2020Date of Patent: June 6, 2023Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.Inventors: John Knoll, Leandro Estebecorena, Stephane Grabli, Per Karefelt, Pablo Helman, John M.

Patent number: 11069135Abstract: A method of transferring a facial expression from a subject to a computer generated character that includes receiving a plate with an image of the subject's facial expression, a three-dimensional parameterized deformable model of the subject's face where different facial expressions of the subject can be obtained by varying values of the model parameters, a model of a camera rig used to capture the plate, and a virtual lighting model that estimates lighting conditions when the image on the plate was captured.Type: GrantFiled: November 12, 2019Date of Patent: July 20, 2021Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.Inventors: Stéphane Grabli, Michael Bao, Per Karefelt, Adam Ferrall-Nunge, Jeffery Yost, Ronald Fedkiw, Cary Phillips, Pablo Helman, Leandro Estebecorena
