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 uncertainty 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.
