With the sensor size, image pixel resolution, focal length, and known subject size, you can back-calculate (well, estimate) the distance between the camera and subject (assuming that the subject is reasonably parallel to the camera sensor plane).
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.
Measure dimensions with iPhone. Use the Measure app and your iPhone camera to measure nearby objects. iPhone automatically detects the dimensions of rectangular objects, or you can manually set the start and end points of a measurement.
7 sie 2023 · Using the Measure app is as easy as pie. Simply open it up and point your camera at whatever object or distance you want to measure. You’ll notice that some yellow dots appear on your screen – these are virtual anchor points that help improve accuracy.

Just launch the app, point your camera at something, and it will measure dimensions of objects in the real world. This is one of the many new features in the iOS 12 update.
Because its two cameras are offset, each with a slightly different view of the scene, the iPhone 7 Plus is able to use the relative shift of objects between them, or parallax, to estimate how far away elements in the scene are from the camera itself.
