Patent ID: 7782453

Claim:
A method for determining with a borescope the dimensions of a missing corner portion of an object under inspection, the object under inspection having a first and a second remaining edges adjacent the missing corner portion, the method comprising: aligning the borescope with the object under inspection for viewing a region containing the missing corner portion; capturing an image of the object under inspection including the missing corner portion; placing a first cursor markers on said image to identify a first points where the first remaining edges of the object under inspection ends and the missing corner portion begins; placing a second cursor marker on said image to identify a second point where the second remaining edge of the object under inspection ends and the missing corner portion begins; placing a third cursor marker on said image to identify a third point on the first remaining edges; defining a first missing portion boundary with said first cursor markers and said third cursor markers; extrapolating a second missing portion boundary from said second cursor marker to an intersection with said first missing portion boundary; and determining the missing portion dimensions using said first and second missing portion boundaries.
