Abstract: Tracking a control object on a stage for a virtual production, including: tracking a control object on the stage with a system that tracks at least one camera used in the virtual production; identifying a location in a virtual environment using tracking information of the control object; and placing virtual assets at the identified location in the virtual environment.

Abstract: Systems, methods, and apparatus to generate training data include receiving a beam of light reflected from a subject and splitting the beam of light into at least a first beam and a second beam; directing the first beam toward a first sensor and the second beam toward a second sensor; sensing and processing the first beam to generate a first video having a first characteristic; sensing and processing the second beam to generate a second video having a second characteristic; and processing the first video and the second video to generate training data.

Abstract: Obtaining depth information using an IR sensor with a beam splitter including illuminating a subject with IR light using an IR light source; receiving reflected light including visible light and the IR light at a beam splitter; splitting the reflected light into two identical beams, a first beam and a second beam, using the beam splitter; receiving and processing the first beam at an IR sensor to pass the IR light and to block the visible light, to generate an IR image; receiving and processing the second beam at a visible light sensor to pass the visible light and to block the IR light, to generate a visible light image; and using a time of flight of the IR light transmitted by the IR light source and received by the IR sensor to calculate a distance of the subject from the beam splitter.
