Abstract
A marker system includes: a first marker; and a second marker; wherein the first marker and the second marker are configured to emit light from one or more light sources coupled to the first marker and the second marker; and wherein the first marker and the second marker are configured to emit the light for detection by a camera. A method performed using a marker system includes: generating light using one or more light sources; emitting the light at a plurality of markers that are coupled to the light sources; and detecting the light emitted from the plurality of markers using a camera; wherein the act of detecting comprises using one or more filters to reduce ambient light to a level that corresponds with a noise level of the camera while allowing light emitted from the markers to be imaged by the camera.
