First Claim
1. An inspection system for locating multiple features on an exterior of an object, the inspection system comprising:
- a fixture for securing the object comprising;
a plurality of nest points for mating with specific positions on the exterior of the object; and
a reference point located at a specific position relative to the nest points and within a best-plane of the object;
a camera positioned normal to the best-plane of the object for obtaining video images of a plurality of the features and the reference point;
a computer in communication with the camera for collecting the video images; and
software for determining actual location of the features relative to the reference point based on the video images.

Abstract
An inspection system for locating multiple features on an exterior of an object includes a fixture, a camera, a computer and software. The fixture secures the object and includes a plurality of nest points for mating with specific positions on the exterior of the object, and a reference point located at a specific position relative to the nest points and within a best-plane of the object. The camera is positioned normal to the best-plane of the object and obtains video imaging of a plurality of the features and the reference point. The computer communicates with the camera and collects the video imaging. The software determines the actual parameters of the features relative to the reference point based on the video imaging.

14. A method for locating multiple features on an object, the method comprising:
-
positioning the object in a fixture such that the fixture mates with the object at specific nest points;
positioning a reference point on the fixture relative to the nest points and within a best-plane of the object;
positioning a camera along a best-plane of the object such that it has a view of multiple features within the best-plane and the reference point;
capturing a video image of the object including a plurality of the features and the reference point;
performing software analysis of the video image to locate actual positions of the plurality of features relative to the reference point. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22)
