I want to calculate the distance between two objects using an iPhone camera.
Suppose I'm standing with my iPhone 10 feet away from the objects. Now, I want to calculate the distance between those two objects.
Suppose these two objects are on a straight horizontal line. So, how can I calculate the distance between those two points?
I have only the one predefine value like 10 feet or 5 feet/meter which is the distance between camera and the object.
From the above information how can I calculate the distance between two point OR distance of maximum width of screen ?
Reference Android App: Speed Gun
