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.
- 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.
- 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.
