Trevista CI Dome Features
The Trevista CI Dome is a hardware and software-based image formation and inspection solution. Using the power of VisionPro software, the Trevista CI Dome enhances inspection processes of parts with shiny or matte surfaces. The built-in Trevista vision tool within VisionPro uses patented “shape from shading” technology to compose high-quality topographical images quickly. Use integrated AI-based vision tools to analyze surface defects and differentiate cosmetic from critical flaws.
The Trevista CI Dome solution helps:
- Decrease scrap rates and costs
- Reduce inspection times
- Catch more flaws, faster
Unmatched image quality
Many shape from shading techniques rely on ring lighting or multiple bar lights, which limit the amount of defect details due to poor lighting angles. The Trevista CI Dome delivers greater detail because it illuminates the component from all angles, revealing more flaws. Using a sequence of images taken from different lighting quadrants, the patented Trevista shape from shading algorithm creates a more detailed set of composite images with higher quality and repeatability, enabling a more robust inspection process.
Faster image processing
High-volume manufacturers require high speed to keep up with demand, deliver exceptional quality parts, and maximize throughput and efficiency. The Trevista CI Dome increases efficiency and throughput by capturing and composing topographical images of part surfaces up to two times faster than other computational imaging solutions. Using the shape from shading tool within VisionPro and diffused dome lighting, the Trevista CI Dome composes high-quality topographic images of contoured parts at very high speed, regardless of orientation or position, which reduces the inspection time required per part.
Highly detailed surface visualization
Manufacturers often accept larger-than-desired overkill rates of their parts to ensure quality and throughput targets, which leads to higher scrap and costs. The diffuse light of the dome captures light reflections from every angle, illuminating concave or convex shapes more effectively, which more accurately captures surface slope information. AI-based vision tools use this information to classify surface defect severity. Assessing and classifying defect severity helps reduce overkill, decrease scrap rates, and lower costs.
