APPLICATION ON THE BINOCULAR VISION INSPECTION TECHNOLOGY OF FREE-FORM SURFACE

Abstract

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.

Key words: Binocular vision probe, Camera calibration, CMM, Free-form surface, High-reflective metallic surface
