Different item heights on the same line [PickMaster 3]

I am running several different projects at the same line. The different projects use different items with different heights. As the camera can only be calibrated for one item height, what can I do?

There are two alternatives to this problem.

  1. If the items do not differ too much, you might get it to work by calibrating the camera on a height that is in between the height of tallest and shortest item used in various projects. There will then always be a small error, but if the height difference is limited, so will the error.
  2. Calibrate different lines and then run projects on lines that are calibrated on the height that corresponds to the item height. This assumes that it is possible to have a good enough focus on both heights.
