How to transfer pixel value to real physical length

Can I using getBlock function to capture the distance between form camera to object ? If it’s possible, then how can I do to transfer the “16-bit X (center) of block in pixels” to physical length?

Thanks All.

Pixy is an object detector. It can detect objects in the image, but determining distance to the object is a different problem.

If you know the size of the object, you can estimate the distance – see

Hope this helps
