Camera Resolution with horizontal field of view of 110 mm: a worked example

This worked example runs the camera resolution numbers for a tougher week than the baseline: horizontal field of view of 110 mm instead of the typical 220 mm. Calculate inspection resolution (mm per pixel) for a machine vision camera by dividing the horizontal field of view by the camera horizontal pixel count, so you can confirm whether the camera has enough resolution to meet your inspection specification.

The inputs for this scenario

  • Horizontal field of view (FOV width): 110 mm (the input this scenario stresses; the baseline uses 220)
  • Camera horizontal pixel count: 2,448 pixels (held at the documented default)
  • Unit conversion factor: 1 x (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Inspection resolution = FOV width / horizontal pixel count x conversion factor.
  • Inspection resolution (mm per pixel) works out to 0.04 mm/px at these inputs, and this is the headline figure for the scenario.
  • FOV per pixel (before conversion) works out to 0.04 value at these inputs.
  • Unit conversion factor works out to 1 x at these inputs.
  • Horizontal pixel count works out to 2,448 value at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where horizontal field of view sits at 220 mm and the headline result is 0.09 mm/px, this scenario comes in 50% below the baseline at 0.04 mm/px.
  • Use it after fixing the FOV to verify the camera has enough pixels to meet your measurement tolerance or defect-size requirement. A result at this level usually justifies acting on the stressed input before touching anything else, because every other figure in the table is downstream of it.

Results at a glance

  • Inspection resolution (mm per pixel): 0.04 mm/px (headline result)
  • FOV per pixel (before conversion): 0.04 value
  • Unit conversion factor: 1 x
  • Horizontal pixel count: 2,448 value
