The foundation of any successful machine vision application lies in the quality of the input image. A high-quality starting point reduces the need for complex software workarounds, allowing developers to focus on core technology development. The key question becomes: are you capturing all the necessary details from your images? Could improving the image quality lead to better results?

In this article, we’ll explore some practical strategies to enhance your machine vision system and achieve superior image quality without breaking the bank.

Overall System Considerations

  1. Vibration Control: If vibration sensitivity is an issue, pay close attention to cabling. Rigid cables serve as excellent transmission lines.
  2. Calibration: Ensure all system components are properly calibrated. Consider purchasing pre-calibrated sub-assemblies from suppliers whenever possible.

Camera Optimization

  1. Resolution Enhancement: Increasing camera resolution can potentially reduce the number of cameras needed in your system.
  2. Color Contrast: Utilize color to create contrast and improve feature visibility.

Lens, Filter, and Lighting Solutions

  1. MTF Evaluation: Verify that your optics have sufficient Modulation Transfer Function (MTF) to resolve scene details accurately. If you’re unfamiliar with MTF analysis, study its impact on imaging systems.
  2. Reflection Management: Minimize reflections by slightly tilting optical elements like enclosures or filters in front of the camera.

Cabling and Interface Best Practices

  1. Standard Interfaces: Use official standard interfaces to ensure future modifications won’t require a complete system redesign.
  2. Camera Link Improvements:
    • Remove cable ties
    • Maintain adequate spacing between cables
    • Avoid sharp bends in cables
    • Reverse one Camera Link cable in a set for improved behavior

Strategic Planning and Partnerships

  1. Parameter Prioritization: Identify essential image-related parameters for your application, then compare solution options based on this list rather than relying solely on supplier brochures.
  2. Long-Term Alignment: Ensure partners share responsibility for achieving your long-term goals. Consider whether you aim to be a market leader or simply offer low-end products.
