I'm new to computer vision. I'm trying to solve a problem that I find interesting. My goal is take a 2 pictures of an object, that is able to move freely (like a ball). then compare the two pictures, to see if the balls elevation has risen. I've looked into examples of finding distance/hight but, it was always with an object with fixed distance. I've looked into projective geometry/other programing libraries but, i've just ended up more confused than finding some direction. I'm not sure what type of resources I need to be looking at. Any advice would be great!
