I'm new to the world of vision software. I want to examine pictures with the following result: I want to detect the screw head that is about in the middle of the picture and calculate it's offset to the real center of the picture.
I came to some result but not really succesfull.
I mostly tried combining Canny edge detection followed by the Circles module.
I tried with completely different pictures and there I had better results.
Does anyone have any idea what I would be doing wrong? How important is the resolution of the pictures? The light?
Am I using the wrong program or should this be no problem for a powerfull program like RR?
