Finding height difference with precision of 1mm using open cv

asked 2018-12-06 04:19:11 -0500

I wants to find the height difference of doors of a refrigerator using open CV with precision of 1 mm. is it possible to achieve this using openCV. I am new to openCV so I wants to know whether the required goal is achievable using openCV or not?(Note: this is required to check weather refrigerator doors are installed correctly or not by finding height difference of doors)

This is probably a precision problem before all, not an image processing issue. A small movement of the camera, or the refrigerator at a slightly different position, and the result is biased.

General rule: try to solve the problem manually: on a set of photos try to see if you can determine which doors are not installed correctly (GIMP has a good measure tool). If you can't measure it manually, the computer won't be able to do it neither.

Maybe another solution (mechanical testing or something similar) could give more reliable results.

If you post an example picture too, maybe we can give you better advice.
