  • Patent number: 11380136
    Abstract: The present description relates to light patterns used in a live action scene of a visual production to encode information associated with objects in the scene, such as movement and position of the objects. A data capture system includes active markers that emit light of a particular wavelength in predefined strobing patterns. In some implementations, the active markers are instructed to emit an assigned signature pattern of light through a signal controller sending signals to a control unit. Various components are synchronized such that pulsing of light corresponds to time slices and particular frames captured by the performance capture system. The data representing the pattern is embedded in illuminated and blank frames. Frames showing the light pattern are analyzed to extract information about the active markers, such as identification of the active markers and objects to which they are attached.
