Abstract

A detection system including a target object having a target object coordinate system, a tracking unit configured to monitor a position and / or an orientation of the target object and generate a target object position signal indicative of the position and / or the orientation of the target object, a camera positioned to capture an image of the target object, an orienting mechanism connected to the camera to control an orientation of the camera relative to the target object, and a processor configured to analyze the image to detect a discrepancy in the image and, when the discrepancy is present in the image, determine a location of the discrepancy relative to the target object coordinate system based at least upon the target object position signal and the orientation of the camera, and then orient the camera and laser to aim at and point out the discrepancy.

Description

technical field [0001] The present disclosure relates generally to detection systems, and more particularly, to systems and methods for locating and detecting differences on target objects, even when the target objects have moved. Background technique [0002] Variances, such as foreign body debris, can present costly and challenging problems during the repair or manufacture of composite structures (eg, aircraft skins). Failure to detect and remove differences can lead to a reduction in the structural integrity of composite structures. Additionally, if discrepancies are not detected early in the composite structure fabrication process, the resulting composite structure may be disposed of, repaired, or in some cases approved through engineering analysis and qualification. Each option will be expensive. [0003] In addition, there may be small differences in size or near the bonding layer, which can cause detection failures. Failure to detect these discrepancies in time can...
