SmartView® Metals

On-Line Detection, Identification, and Visualization of Metal Defects

SmartView Metals has become the most trusted surface inspection system worldwide. With more installations on more lines than any surface inspection system ever, SmartView is relied upon around the world by virtually every major flat rolled products producer. For many of them, SmartView is the de-facto standard in on-line defect detection and identification.

The SmartView system detects irregularities or defects on the surface of the metal strip. SmartView then identifies each defect using our patented SmartLearn® Multi-Step Classifier. The defect image is displayed for the operator to see. All information and images are available in real time and can be stored in our database for future use. Reports can be created and formatted to fit the needs of every mill.

Our Value

SmartView provides more value to users than any other surface inspection system.

  • Improve product quality
  • Maximize yield
  • Detect, identify, and visualize defects before value added processes
  • Reduce the need for manual inspections
  • Provide the reports you need in a form you can use

We have been successfully inspecting metals surfaces for two decades. In fact, SmartView systems inspect over 1 billion square meters of metal every day! We have metals customers on all continents and more metals customers worldwide than anyone else in the industry. More companies guarantee their quality with SmartView systems than any other surface inspection system.

Our Detection

The SmartView Metals system is highly modular, allowing the use of appropriate technology for your application using standard system components. We install appropriate light and camera configurations for each line. Some allow strip inspection while going over a roller and others allow inspection on the unsupported strip. Cognex offers the most comprehensive selection of lighting solutions in the industry, applying collimated, diffuse, or side lighting depending on your application needs. For example the use of collimated light allows us to employ our exclusive synchronized view technology with two sets of cameras looking into the surface from different angles. In addition, our collection of thresholding algorithms can be optimized for your particular surface and requirements, all performing on-line in real time. You never have to wait for SmartView results.

Our Classification

The SmartLearn® Multi-Step Classifier is a patented classification tool set for SmartView surface inspection systems. SmartLearn provides the flexibility to implement classification schemes tailored to your particular process and requirements. The advanced SmartLearn architecture allows the use of various learning classifiers. Combining automatic learning classification with expert knowledge, SmartLearn maximizes the potential of your inspection system for improved product quality, higher production yield, and decreased customer returns.

Our Through-Process Visibility

SmartView Screenshot

The Windows®-based SmartView Metals system, connected to your mill network, provides information for mill-wide users, from the manufacturing floor to the front office. SmartView Metals uses industry standards like OPC and ODBC to ensure easy integration with other plant business, production, and quality systems. A real-time operator interface shows current inspection results on-line all the time. The Open Network Inspection Viewer, distributed across the plant network, enables any user to view current or historical inspection results remotely from any step in production from hot mill to the finishing line.

SmartView Can Do More
SmartView users can easily upgrade their system with powerful capabilities that are not available anywhere else.

Our Surface Quality Monitoring software automatically measures and reports the surface quality characteristics of the coil in real time. For the first time you can have a measurement of overall surface properties such as spangle, cloudiness, roll chatter marks, or surface roughness. It can even predict post-processing properties of the product when it is being produced.

SmartView Streaming Video can combine defect detection with full-width video recording of the strip. Watch in real time or go back and replay any archived coil to virtually inspect the strip. All this is done with standard SmartView cameras and lighting.
