Dual camera in the phone as a stereo pair?

Question

Android

There is a xiaomi redmi note 7 phone with a dual main camera. I want to use it as a stereo pair. Can I receive video (photos) from two cameras at the same time?

Answer 1

I won’t talk about the software reasons that prevent such an application (you yourself understand that for this you need someone to write an appropriate application, but it doesn’t seem to be observed yet). I will tell you why no one will write it, since the subject is physically impossible.
1. Very small stereo base. If the distance between the lenses is of the same order as the distance between human eyes, we can get stereo images of objects at a distance of no more than tens of meters. If we want to go further, then the base should be like that of an artillery stereo sight (up to a meter). And we have - 1 ... 2 centimeters. With such a base, you can only make stereo shooting of objects located very close to the device (centimeters). Is this what you wanted?
2. We need exactly the same cameras. But in your case, they are completely different. This means that the images in a stereo pair will also be completely different. So how do you watch them then? Well, it will be such a strabismus ...
In general, the idea is hopeless.
