How can I recognize which image is left?

There are two overlapping images, one shot to the left and one shot to the right. After I load these two images, how can I know which one is to the left

What’s your problem exactly?

the best way is to know which camera is which “eye”, and which camera took each picture.

you as a human can tell from visual ques. display both in front of you and swap back and forth.

if an object moves in the picture, the object did not move but the view moved, so you have to think about what the “moving object” means for which “eye” you’re seeing through.
