<p>A web inspection system (10) for analysis of a moving web of material (50) records and stores continuous sequences of the web (50). The web inspection system (10) includes a camera (20) for recording the continuous sequence of the web (50), an encoder (60) for synchronizing movements of the web (50) with the video image being recorded, and an Image Processing System (IPS) (30) including a real time video disk for storing the image of the web (50) and for displaying (40) the continuous sequence of web image on a video display. The IPS (30) is also utilized for detecting faults or features and for categorizing the faults or features detected. The entire web (50) is recorded and the image can be viewed either interactively while the image is being recorded or at a later time. The recorded image of the web can be played back at a slower speed to allow for a more detailed inspection of the web (50). The sequence image can be analyzed to build a defect image database. The web inspection system (10) can also be utilized for sorting and displaying defect information.</p> |
