I'm working on an object tracker where I need to report the azimuth and elevation of targets. Both values should be scaled from degrees to unsigned 32-bit integers. For now I can ignore lens distortion, assume Z=0, and make an arbitrary North (the center of the image?).
The images are single frames taken at 60fps. I don't know the size of the object a priori, but I can assume that each pixel occupies a known fixed size because I really don't care about Z at this point.
Once I have the image coordinates how to I transform them to azimuth and elevation?
