Check if it is possible to create a python application to aid autofocus micro adjustment on a DSLR. There are some commercial applications that are capable of that, such as Reikan FoCal (https://www.reikanfocal.com).
The goal here is to create a small python app that maybe runs on a raspberry, controls the camera via usb using gphoto2 library and process the resulting image using openCV library. Then correction values wil be output, so the user can input in the camera (has to be done manually).
This project is one of its kind!
