Abstract
A system and a method for detecting a damaged or missing machine part. The system includes an image capturing device for capturing images of the machine and a processor for processing the captured images. The system may further include a sensible output for providing an indication of a damaged or missing machine part. The method includes capturing images of the machine against a background which moves relative to the machine over time, selecting a pair of time-separated images from the captured images, generating a displacement image from the pair of images, comparing the machine from the displacement image with a machine model, and identifying a damaged or missing machine part from the comparison of the displacement image with the machine model. The method may further include providing a sensible output which indicates a damaged or missing machine part.
