Evaluation

In this application, surface flaw detection is used to detect defects in the carpet surface. For each 12 inch section, a system will be needed. Multiple cameras/lights will be needed to inspect a large piece of carpet for defects. The carpet must be fixtured for the application to be robust. The entire inspection takes roughly 140 m/s. A large amount of light is needed due to the speed of the application.
