【Abstract】 A non-contact free-form surface measurement system is built which consists of CMM and a Binocular vision probe. With a virtual 3D target in form of a grid plate, all the intrinsic and extrinsic parameters of CCD camera including the uncer-tainty of image scale factor and optical center of camera can be readily calibrated. Through measuring cylindrical section and surface of gauge block, this system is viable to measure free-form surface and high-reflective metallic surface.更多还原
