How to use this tool

  1. Enter image speed, readout ms, height.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "image_speed": 1200,
  "readout_ms": 20,
  "height": 4000
}

Accuracy and scope

Constant horizontal image velocity and top-to-bottom readout; excludes camera rotation, exposure blur and partial-height readout.
