It is imperative Thorough documentation provides peace of mind to have a clear and concise picture of the direction for both you and your customers. in which you want to proceed. The obstacle within this process is that facet of human nature striving to meet our highest expectations beyond reason. Results at a glance All of the defects detected can be viewed in a condensed 2D-form once the inspection process has been completed. A histogram reflects the fre- quency of defects along or across the direction of strip travel.

This provides you with the decisive advantage of, for example, doubling the longitudinal resolution when you re- duce the strip speed during an inspection proce- dure. So the Fire system automatically adapts to your quality requirements. Feature extraction The next step is the calculation of the features of every defective region. This involves the definition of the defect by identifying approximately 100 features such as width, length, or contrast. With this, the operator retrieves the most important and meaningful information at a glance. The cameras scan the surface line by line and produce a two-dimensional picture that has 256 gray scales. The pixel resolution can be set to suit your particular requirements as the number of pixels can be specified anywhere between 1000 and 7000. The images produced in this way are then prepared by the image-processing system. Detected defects are allocated to the appropriate defect classes and presented clearly on the screen.
