Hello. Understanding opencv in Bradsky’s book Learning OpenCV. I started the example 12-1 "Bird's eye view", everything is fine - it works, it even shows something. Because I do not really understand the essence of "Bird's eye view" (and there is practically no material on it), please explain why it is needed, what the input parameters should be and what we should get at the output. Or indicate where you can read about it. Thanks in advance.
