Abstract
Localization and tracking system. The system includes at least one laser mounted for pointing its beam at arbitrary locations within a three-dimensional space. An object within the three-dimensional space supports a screen at its top for receiving the laser beam to create a shaped image on the screen. The shaped image on the screen is observed by a camera and computing apparatus determines the location of the object in the three-dimensional space from pointing parameters of the laser and from shape and center points of the shaped image on the screen.
