Patent number: 11232591Abstract: A system generates a user hand shape model from a single depth camera. The system includes the single depth camera and a hand tracking unit. The single depth camera generates single depth image data of a user's hand. The hand tracking unit applies the single depth image data to a neural network model to generate heat maps indicating locations of hand features. The locations of hand features are used to generate a user hand shape model customized to the size and shape of the user's hand. The user hand shape model is defined by a set of principal component hand shapes defining a hand shape variation space. The limited number of principal component hand shape models reduces determination of user hand shape to a smaller number of variables, and thus provides for a fast calibration of the user hand shape model.Type: GrantFiled: July 24, 2020Date of Patent: January 25, 2022Assignee: Facebook Technologies, LLCInventors: Christopher David Twigg, Robert Y.

Patent number: 10719953Abstract: A system tracks poses of a passive object using fiducial markers on fiducial surfaces of a polygonal structure of the object using image data captured by a camera. The system includes an object tracking controller that generates an estimated pose for a frame of the image data using an approximate pose estimation (APE), and then updates the estimated pose using a dense pose refinement (DPR) of pixels. The APE may include minimizing reprojection error between projected image points of the fiducial markers and observed image points of the fiducial markers in the frame. The DPR may include minimizing appearance error between image pixels of the fiducial markers in the frame and projected model pixels of the fiducial markers determined from the estimated pose and the object model. In some embodiments, an inter-frame corner tracking (ICT) of the fiducial markers may be used to facilitate the APE.Type: GrantFiled: March 27, 2018Date of Patent: July 21, 2020Assignee: Facebook Technologies, LLCInventors: Yuting Ye, Robert Y.

Patent number: 10706584Abstract: A system tracks a user's hands by processing image data captured using one or more passive cameras. The system includes one or more passive cameras, such as color or monochrome cameras, and a hand tracking unit. The hand tracking unit receives the image data of the user's hand from the one or more passive cameras. The hand tracking unit determines, based on applying the image data to a neural network model, heat maps indicating locations of hand features of a hand shape model. The hand tracking unit may include circuitry that implements the neural network model. The neural network model is trained using image data from passive cameras, depth cameras, or both. The hand tracking unit determines a hand pose of the user's hand based on the locations of the hand features of the hand shape model. The hand pose may be used as a user input, or to render the hand for a display, such as in a head-mounted display.Type: GrantFiled: May 18, 2018Date of Patent: July 7, 2020Assignee: Facebook Technologies, LLCInventors: Yuting Ye, Robert Y.

Patent number: 10489958Abstract: A system includes a computing device that includes a memory configured to store instructions. The system also includes a processor configured to execute the instructions to perform a method that includes receiving multiple representations of an object. Each of the representations includes position information of the object and corresponds to an instance in time. For at least one of the representations, the method includes defining a contour that represents a movable silhouette of a surface feature of the object. The method also includes producing a deformable model of the surface of the object from the defined contour and from the at least one representation of the object.Type: GrantFiled: August 1, 2017Date of Patent: November 26, 2019Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.Inventors: Ronald Mallet, Yuting Ye, Michael Koperwas, Adrian R. Goldenthal, Kiran S. Bhat

Patent number: 9858700Abstract: Systems and techniques are provided for transferring changes in animation data between geometric models of a character having different resolutions. For example, systems and techniques are provided for transferring changes in geometric properties between the geometric models. A method may include obtaining a first geometric model of the character and a second geometric model of the character, the geometric models having different resolutions with different numbers of data points. The method may further include determining one or more correspondences between data points of the first geometric model and data points of the second geometric model. The correspondences include one or more data points of the first geometric model that overlap with one or more data points of the second geometric model.Type: GrantFiled: May 13, 2015Date of Patent: January 2, 2018Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.Inventors: Rachel Rose, Yuting Ye, Scott Jones

Patent number: 9317954Abstract: Techniques for facial performance capture using an adaptive model are provided herein. For example, a computer-implemented method may include obtaining a three-dimensional scan of a subject and a generating customized digital model including a set of blendshapes using the three-dimensional scan, each of one or more blendshapes of the set of blendshapes representing at least a portion of a characteristic of the subject. The method may further include receiving input data of the subject, the input data including video data and depth data, tracking body deformations of the subject by fitting the input data using one or more of the blendshapes of the set, and fitting a refined linear model onto the input data using one or more adaptive principal component analysis shapes.Type: GrantFiled: December 26, 2013Date of Patent: April 19, 2016Assignee: LUCASFILM ENTERTAINMENT COMPANY LTD.Inventors: Hao Li, Jihun Yu, Yuting Ye, Christoph Bregler
