Machine Vision

  • Camera Selection: https://ocularcomponentmv.blogspot.com/2014/04/machine-vision-lens-and-camera.html

  • Lens mount quality

    • CS < M12 < C (best for machine vision)
    • Use C mount for image sensors > 1/8"
    • M12 is suited only for sensors upto 1/8". Cheap M12 are only good upto 1/3". Expensive M12 do not have as much distortion as cheap M12 and are suitable for high resolution cameras and sensors upto 1/8".
    • CS mount is bad for machine vision. Mostly used in CCTV cameras.
  • CS mount cameras can support M12 and C mount lenses with adapters.

Considerations

  • Sensor size
  • FoV
    • At a fixed pixel size and a fixed aspect ratio your field of view will increase with increasing number of pixels. With this relation it is thus possible to decide between the IMX252 and IMX253
  • Working Distance
  • Optimized for Application (e.g. M12 is only distortion optimized for short distances, while C is optimized for more aberrations).
    • Find which aberrations can be corrected and which ones are acceptable, etc.
  • Environment (for damping, etc.)
  • Interface
    • MIPI CSI 2/3 | Camera Link | USB 3.0 | Gig-E | CoaXPress | SLVS-EC | Sub LVDS
  • Range-estimation
    • ToF
    • Parallax
