Synchronised Camera View Provides Optimum Process Insights

Thanks to high-­performance line scan camera technology, the use of synchronized camera views for each application provides the optimum combination. This allows the flexible use of a number of different configuration and inspection angles. The configuration of Wieland’s DO50 is described by image processing experts as synchronized view processing. As outlined above, two lines of bright field and dark field cameras are installed. This means that even the most diverse of reflection properties can be reliably identified. Because Smart View combines the bright field and dark field defect patterns in real time, defect types can be accurately classified.

Split-Second Classification

Smart View’s advanced processing software enables an automatic detection and classification of surface defects based on pre-determined parameters. This also ensures that acceptable surface features are not falsely detected. Once the defect has been detected and classified, it is presented to an experienced operator to assess the defect pattern in detail. The entire process of image capture, image analysis and data exchange takes a split second. In this way, positional data, the grayscale value, orientation axes and segmentations are combined as a defect-­specific data packet. Overall, Smart View determines a unique set of characteristics for each defect pattern. The data is transmitted once the final process step has been completed.

Unlike the first surface inspection systems used at Wieland, which was a costly customized solution, today’s standardized, “off the shelf” Smart View systems provide effective, cost-efficient defect detection across the entire company. The flexible system is the result of more than 20 years’ research, development and experience in selecting the right combination of industrial cameras, variable lighting and high-performance image processing software. Wieland uses a total of 25 Smart View surface inspection systems worldwide.

A Closer Look on Quality Control

These are identical in terms of structure but are individually optimized to the specific application. This combination of standardization and customization reduces both the upfront purchase costs (compared with a bespoke solution) and the cost of start-up, maintenance and worldwide data exchange. Wieland can therefore put its trust in a reliable and fast surface inspection at all production sites throughout the world. With these systems, Wieland’s products meet the highest quality standards, regardless of whether they are produced in Vöhringen, Villingen, Langenberg, Birmingham, Wheeling or Singapore.

Not only does Smart View identify and classify defects quickly and thoroughly, it is also easy to set up, thanks to its sophisticated, intuitive configuration. By utilizing these tools, the Project Manager from Ametek Surface Vision can have the system up and running a short time after the mechanical installation is complete. From there, the operators can easily maintain the system and adjust it to many different operating conditions.
