Please find attached a picture of my reference image, my Aligment Marker, and my ROI Configuration.

And the recognized value is the following:

Is this an error in my configuration or is the image being recognized incorrectly?

If the image is rotated mechanically by realigning the ESP32-CAM and not digitally when creating the reference image, then everything works.
