US Patent:

47258837, Feb 16, 1988
Filed:

Jul 18, 1986
Appl. No.:

6/886844
Inventors:

William G. Clark - Murrysville PA
Lee W. Burtner - Elizabeth PA
Francis X. Gradich - Elizabeth PA
Assignee:

Westinghouse Electric Corp. - Pittsburgh PA
International Classification:

H04N 718
US Classification:

358100
Abstract:

An optical inspection system for tubular products utilizes a feeler for engaging the internal surface of the tube to be inspected and a miniature charge coupled device video camera for viewing the interface between the feeler and the tube. An image processing computer responsive to the output of the video camera produces information for rapidly assessing damage or distortion of the tube. The camera is pulled or pushed through the tube while continuously monitoring the optical contrast between the feeler and the tube wall. The camera image of the tube ID is fed to the image processing computer to determine and record changes in ID contour is a function of the axial position of the camera and feeler. These data in turn can be used in tubing life prediction considerations. The data may be analyzed manually if desired.
