Abstract:
A method of aligning a 3D CAD model to a test object in a machine vision system comprising steps of orienting the 3D CAD model in a model window, placing the test object on a motion stage in an orientation approximately matching the orientation of the 3D model, taking a video image of the test object with the video camera and extracting a peripheral boundary in a datum plane normal to the viewing axis of the video camera, extracting a silhouette boundary of the 3D model in a corresponding datum plane, relatively positioning the silhouette boundary of the 3D model to match the peripheral boundary of the test object using a fitting algorithm, and matching coordinates of points in the 3D model to coordinates of corresponding points of the test object referenced within the corresponding datum plane and along the viewing axis.

Claim (Index 1):
A method of aligning a 3D CAD model to a test object in a machine vision system having coordinate axes including a viewing axis of a camera, comprising steps of:\n orienting the 3D CAD model in a model window of the machine vision system for exposing features of the CAD model that correspond to features of the test object intended for measurement; placing the test object on a stage of the machine vision system in an orientation approximately matching the orientation of the 3D CAD model; taking an image of the test object on the motion stage with the camera and extracting a peripheral boundary in a datum plane normal to the viewing axis of the camera; extracting a silhouette boundary of the 3D CAD model in a corresponding datum plane; relatively positioning the silhouette boundary of the 3D CAD model to match the peripheral boundary of the test object in the corresponding datum plane using a fitting algorithm; and matching coordinates of points in the 3D CAD model to coordinates of corresponding points of the test object referenced within the corresponding datum plane and along the viewing axis.
