Abstract
An active marker apparatus is provided for securely affixing active markers to a wearable article of an object in a performance capture system. The active marker light components coupled to a strand, are inserted into a receptacle to position the active marker light components onto the wearable article. A gap is provided in a chamber between the active marker light component and an interior surface of a protrusion portion of the receptacle. At least a section of the protrusion portion permits light emitted from the active marker light component into the chamber, to diffuse in a manner that allows the light to be easily detected by a camera in the live action scene. Each active marker light component is locked into place in a respective receptacle by one or more channels that receive the strand. A cap fitting may further assist in securing the receptacle to the wearable article and optionally aid in visual detection of the receptacle.
