Abstract
Aspects include a method, system, and computer program product for determining the position of an object relative to a reflective surface. A method includes acquiring an image of an object and the reflective surface with a camera, the camera positioned adjacent the reflective surface. The object is identified in the image. A reflection of the object on the reflective surface is identified in the image. Three-dimensional coordinates of at least a portion of the object are determined based at least in part on the identifying of the object and the reflection of the object in the image. It is determined when the object is moving relative to the reflective surface. The position of the object is tracked during the movement.
