Abstract
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.
