Hi Nour,
One of the challenges with vision is to convert accurately from a 2D still image to a 3D space.
For this to be accurate, you need to have a reference distance within the image. Ideally, at the same distance / focus point of your features.
这个例子中利用的事实distance from the camera to the features is consistent, thus allowing us to find a constant pixel/mm ratio and camera height experimentally.

What exactly are you trying to achieve?
Are you trying to do path correction with a camera to be dead centre with the mounting holes?
How far from the mounting holes is your programmed path?
Are you trying to record the mounting holes positions in 3D space?
How accurate your application needs to be?
