I have pixel coordinates in one plane, am I able to transform them to a new plane using homography and then convert to real world coordinates?

I am using a DeepSORT to gather the x and y coordinates of an object. I am using homography to get a zoomed in bird's-eye-view of a specific portion of the video. I know the real-world distances of the area I zoom into, and want to know the real…
