Described are targets for use in optical tracking, as well as related methods. A target comprises a plurality of light dispersers, optically coupled to at least one light source. The light dispersers are illuminated for detection and tracking by a tracking system. In some implementations, the at least one light source is optically coupled to the plurality of light dispersers by a plurality of light directors. In other implementations, the at least one light source includes a plurality of light sources positioned within or proximate to the plurality of dispersers. In some implementations, dispersers are lenses; in some implementations, dispersers are light scattering elements. Targets include or are coupled to a power source. In some implementations, targets include additional electrical components which utilize power from the power source.

Active targets for tracking, and methods for assembling and using the same

Provided are optically detectable markers for tracking, as well as related methods. A marker comprises a mask unit and a (removable) cartridge comprising an optically detectable surface exposed through at least three faces of the mask unit. Respective materials present a measurable contrast under optical detection conditions. An optical detectable surface can be detectable using IR and a contrasting surface is not. Faces can define openings to the cartridge. The cartridge can comprise a sheet of optically detectible material foldable to fit into the mask unit. A sheet can provide multiple connected cartridges. Securing devices including any of a support unit, a clip, a magnet, an adhesive, etc., can secure a cartridge in a mask unit. A marker, or maker kit, may comprise a plurality of mask units and cartridges connected via a marker body. Some of the mask units may be on different planes in such a marker.

Optically detectable markers for tracking, and methods for manufacturing, assembling, and using the same

Described are targets for use in optical tracking, as well as related methods. In some implementations, a target comprises a planar surface with an optically detectable pattern thereon, and at least one protrusion extending from the planar surface. In other implementations, a target comprises a planar surface with an optically detectable pattern thereon, with a specular reflective region. The optically detectable pattern provides accurate position information of the target, and provides accurate orientation information of the target about a first axis, but may not provide accurate orientation information of the target about other axes. The at least one protrusion or the specular reflective region provide accurate information of orientation of the target, particularly orientations about axes other than the first axis.
