  • Reduce customer complaints and improve economic benefits
  • Definition of automatic levels of products for different customers
  • Data mining, analysis and application of front and back process inspections
  • Typical components of smart manufacturing and enhance brand effect

The system uses standard industrial cameras, lenses, and light sources, optical designs that meet application scenarios, image AI intelligent processing units, and industrial-grade hardware systems that meet the steel site environment. It adopts a scientific and advanced industrial inspection software platform, excellent inspection algorithm and AI model, and has a massive defect database. It can detect holes, stains/black spots/mosquitoes, corrosion points/oxides, scratches/scratches, concave/convex points/foreign matter indentation, roller marks, low-contrast roller marks, peeling, scarring, oil stains/oil spots, missing coating, zinc slag and zinc ash, peeling/wrinkling, structural defects, etc.

Hardware system and software system

It adopts standard industrial high-speed line scan cameras and high-resolution digital cameras. Various camera models can be selected for inspection, 2k/2048, 4k/4096, 8k/8192, 12k/12288, 16k/16384 pixels. The maximum line scan speed (line frequency) can reach 200,000 lines/second; the scanning frequency can be automatically adjusted according to the change in vehicle speed. High resolution reduces the number of applied cameras, reduces costs, and has higher accuracy. Convenient integration, easy maintenance, and standardized spare parts. Low cooling requirement (no cooling is required if the ambient temperature is below 45°C). A customized camera protection cover is installed to extend the camera life.
