Increasing the speed of a production line often requires updating existing vision systems to maintain inspection quality. Subpixel explores how to balance camera and lens parameters to ensure that smart cameras and machine vision systems continue to deliver sharp, accurate images even on faster lines.
Key Considerations for Vision System Adjustment
- Exposure Time vs. Motion Blur
Faster production speeds increase the risk of motion blur. Reducing exposure time—either electronically or by adjusting the lens aperture—helps capture sharp images. - Depth of Field (DoF)
Increasing the lens aperture allows more light onto the sensor but reduces DoF. Only objects within this range appear sharp. Selecting the right lens and aperture balance is critical to avoid out-of-focus images. - Lens Focal Length
Switching to a lens with a different focal length can improve DoF and field of view. For example, shorter focal lengths provide a wider view but reduce pixels per millimeter, affecting measurement precision. - Lighting Adjustments
Increasing illumination intensity can compensate for shorter exposure times and smaller apertures, maintaining image quality without sacrificing speed.
Business Benefits
- Maintain inspection accuracy at higher production speeds
- Optimize vision system performance with minimal hardware changes
- Reduce defects and rework through precise visual inspection
- Support automation and Industry 4.0 initiatives
Conclusion
Adjusting machine vision systems for faster production lines requires careful balancing of exposure, aperture, depth of field, focal length, and lighting. Subpixel can help evaluate your vision setup and provide tailored recommendations to maintain high-quality, automated inspections.
