I want to make a project where there would be two objects. I want to track them in relation to each other. And I want to know if the objects are in the same 2D plane (Z for instance).
I want to ask which kind of sensros should I use?
I looked up video tracking but it looks too complicated for the task.
I thought about tracking position of objects in magnetic field, but could not find the sensors and overall task seems complicated aswell.
Thank you in advance for your help!
