  • Patent number: 10812693
    Abstract: 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.

  • Patent number: 10796489
    Abstract: An immersive content presentation system can capture the motion or position of a performer in a real-world environment. A game engine can be modified to receive the position or motion of the performer and identify predetermined gestures or positions that can be used to trigger actions in a 3-D virtual environment, such as generating a digital effect, transitioning virtual assets through an animation graph, adding new objects, and so forth. The use of the 3-D environment can be rendered and composited views can be generated. Information for constructing the composited views can be streamed to numerous display devices in many different physical locations using a customized communication protocol. Multiple real-world performers can interact with virtual objects through the game engine in a shared mixed-reality experience.

  • Patent number: 10109062
    Abstract: System and methods are provided for a non-coherent point tracking process that allows unknown camera motion to be estimated. One or more edges can be identified in images captured by a camera when shooting a scene. For each of the identified edge in the images, at least one tracking object can be placed arbitrarily on the edge. The positions of tracking objects in the images can then be used to estimate a camera motion. In some embodiments, two tracking objects can be placed arbitrarily on the edge to represent the edge and move along the edge arbitrarily from image to image where the edge appears. Multiple of such edges can be identified in the images and camera motions in multiple directions can be estimated based on the identified edges and combined to obtain a combined camera motion indicating the camera's movement in a 3D space when shooting the scene.

  • Patent number: 9818201
    Abstract: Methods and systems efficiently apply known distortion, such as of a camera and lens, to source image data to produce data of an output image with the distortion. In an embodiment, an output image field is segmented into regions so that on each segment the distortion function is approximately linear, and segmentation data is stored in a quadtree. The distortion function is applied to the segmented image field to produce a segmented rendered distortion image (SRDI) and a corresponding look-up table. To distort a source image, a location in the output image field is selected, and the uniquely colored segment at the same location in the SRDI is found. The look-up table provides the local linear inverse of the distortion function, which is applied to determine from where in the source image to take image texture data for the distorted output image.
