Abstract
A method and apparatus for identifying the position of an object that is movable in a determined three-dimensional zone by means of a video camera (20) or the like mounted on the movable object (14), the camera (20) being capable of being swivelled to sight targets (22) disposed around the movable object (14) and to enable the position and the orientation of said object to be determined accurately by triangulation. The invention is particularly applicable to accurately determining the position and the orientation of a sensor or a tool mounted on a robot.
