1. A detection system comprising: a target object having a target object coordinate system; a tracking unit configured to monitor at least one of a position and an orientation of said target object and generate a target object position signal indicative of said at least one of said position and said orientation of said target object; a camera positioned to capture an image of said target object; an orienting mechanism connected to said camera to control an orientation of said camera relative to said target object; and a processor configured to analyze said image to detect a discrepancy in said image and, when said discrepancy is present in said image, determine a location of said discrepancy relative to said target object coordinate system based at least upon said target object position signal and said orientation of said camera.
