Abstract
Embodiments include system and processes for tracking objects using a camera. An optical marker dictionary including one or more optical markers is generated, the optical markers being optically distinct indicators. An optical marker within the optical marker dictionary is associated with and affixed to an object. A processor is in communication with the camera, receiving image data from the camera and applying computer vision to the image data in order to detect the presence of one or more optical markers within the optical marker dictionary within the image data. The processor determines camera position information and applies computer vision to the image data in order to determine relative position information for the detected optical markers and projects a position from the camera to a detected optical marker.
