In-line deflectometry for fully automated paint inspection in automotive industry

With PAINTSCAN, ISRA VISION presents a sensor innovation for the inspection of painted surfaces. The technology combines the precision of deflectometric 3D measuring methods and the speed of 2D surface inspection. The result is in-line deflectometry, an innovative and worldwide unique method setting new standards in process-integrated quality assurance. Integrated into the well-proven complete system Car Paint Vision, PAINTSCAN goes beyond the mere detection of defects: users can three-dimensionally measure defects to receive thorough information in a short time.

A further development of classic deflectometry enables the automated inspection of painted surfaces: in-line deflectometry only requires a single camera shot to identify defects. Thus, PAINTSCAN can be mounted onto a continuously moving robot arm to deliver fast and repeatable results. Previously, users had to use time-consuming stop-and-go processes that require multiple images. Now, all topographic and non-topographic paintwork defects may be measured with highest reliability, including coating and pigment irregularities, inclusions, scratches and dents.

The sensor is based on powerful technological components. It integrates high-resolution Gig-E cameras, a latest-generation processor and special LED Matrix illumination. The components provide the basis for an ultra-fast and highly precise 3D paint inspection. Data processing is performed in almost real time, enabling a reliable high-speed in-line monitoring. Sensors with a resolution of 15 µm provide exact and fully automated results that had not been possible with previously available technology.   

The modern software assists users in the rapid start-up of the technology, providing them with a step-by-step guide to set-up and sensor calibration.
