Cognex Corporation is launching VisionPro Surface, a vision software package for inspecting the surface of materials. VisionPro Surface combines a revolutionary new visual defect detection and classification technology with a simple user interface to enable accurate defect detection, classification, and surface texture assessment during the manufacturing process.
“VisionPro Surface makes the cost savings and quality improvements of automatic surface inspection available to production lines where more complex surface inspection solutions are not practical or economically viable,” said Markku Jaaskelainen, executive vice president and business unit manager for Vision Software. “Manufacturers in industries such as solar energy, architectural glass, high-end plastics, material coating and other converting industries can achieve a quick return on investment by monitoring process efficiency, and identifying and eliminating defective material before it is shipped to customers.”
Unlike traditional surface inspection technologies that use signal processing to detect defects, VisionPro Surface works by monitoring the visual appearance of the material.
Using statistical analysis, VisionPro Surface automatically identifies potential defects on the material’s surface and classifies the defects into groups based on similarity in contrast, texture and/or geometry. During the training phase the user simply adjusts the system’s sensitivity for defect detection, and assigns names or values for defects to distinguish between different types. During production the system automatically classifies each defect according to the categories defined by the user.
