A method of content production includes generating a survey of a performance area that includes a point cloud representing a first physical object, in a survey graph hierarchy, constraining the point cloud and a taking camera coordinate system as child nodes of an origin of a survey coordinate system, obtaining virtual content including a first virtual object that corresponds to the first physical object, applying a transformation to the origin of the survey coordinate system so that at least a portion of the point cloud that represents the first physical object is substantially aligned with a portion of the virtual content that represents the first virtual object, displaying the first virtual object on one or more displays from a perspective of the taking camera, capturing, using the taking camera, one or more images of the performance area, and generating content based on the one or more images.

Camera calibration tool

A motion capture tracking device comprising a base portion including a first alignment feature, a first magnetic element and an attachment mechanism operative to mechanically couple the base portion to a rod, a detachable end cap configured to be removably mated with the base portion, and a plurality of motion capture markers coupled to the end cap. The detachable end cap can include a second alignment feature and a second magnetic element, such that, during a mating event in which the detachable end cap is coupled to the base portion, the second alignment feature cooperates with the first alignment feature to ensure that the base portion and detachable end cap are mated in accordance with a unique registration and the second magnetic feature cooperates with the first magnetic feature to magnetically retain the detachable end cap in physical contact with the base portion upon completion of the mating event.

Cornergrid system

A method of generating unrecorded camera views may include receiving a plurality of 2-D video sequences of a subject in a real 3-D space, where each 2-D video sequence may depict the subject from a different perspective. The method may also include generating a 3-D representation of the subject in a virtual 3-D space, where a geometry and texture of the 3-D representation may be generated based on the 2D video sequences, and the motion of the 3-D representation in the virtual 3-D space is based on motion of the subject in the real 3-D space. The method may additionally include generating a 2-D video sequence of the motion of the 3D representation using a virtual camera in the virtual 3-D space where the perspective of the virtual camera may be different than the perspectives of the plurality of 2-D video sequences.

Motion-controlled body capture and reconstruction

Methods and systems are disclosed for calibrating a camera using a calibration target apparatus that contains at least one fiducial marking on a planar surface. The set of all planar markings on the apparatus are distinguishable. Parameters of the camera are inferred from at least one image of the calibration target apparatus. In some embodiments, pixel coordinates of identified fiducial markings in an image are used with geometric knowledge of the apparatus to calculate camera parameters.

Automated camera calibration methods and systems

An apparatus is disclosed which may serve as a target for calibrating a camera. The apparatus comprises one or more planar surfaces. The apparatus includes at least one fiducial marking on a planar surface. The set of all planar markings on the apparatus are distinguishable.

Calibration target for video processing

An apparatus is disclosed which may serve as a target for calibrating a camera. The apparatus includes a hollow body having an interior surface, an exterior surface and at least one window formed in the hollow body through which the interior surface is visible. A plurality of distinguishable fiducial markers are arranged in a predetermined pattern along the interior and exterior surface of the hollow body. The fiducial markers can be distinguishable such that, for any given image of the target captured by a camera, there is only one position, rotation, distortion value, and focal length for the camera of interest.
