Patent ID: 7429999

Claim:
A camera calibrating target for use with a laser source capable of generating a beam of coherent light defining a calibration plane, said camera being characterized by a field of view in the direction of an optical axis forming a predetermined angle with said calibration plane, said beam intersecting the field of view of said camera to define an object imaging area, said target comprising: a frame defining a coplanar arrangement of reference points having known position coordinates within an object reference system associated with said frame and defining at least two dimensions, said frame being capable of being disposed in a camera calibration position wherein said coplanar arrangement of reference points is substantially parallel to said calibration plane; and an arrangement of light reflecting members protruding from said arrangement of reference points in a direction substantially perpendicular thereto, each said member having a light reflecting surface substantially parallel to said direction so as to extend within said object imaging area when said frame is disposed in said camera calibration position to allow said camera to capture an image formed by illuminated portions of said light reflecting members.
