How to create a 3D model from a set of photos?

Question

Android

There is a task to make the application part of the functionality of which will be the creation of a 3D model of an object. That is, the user takes several photos of the object from different angles, after which the application gives him a 3D model.
What specifically interests you:
1) Are there ready-made APIs that can glue several photos into a 3D model, maybe paid ones (I suspect there are no free ones :) )?
2) Same only SDK. It is important that you can connect on the Android client. Not a problem if you have to use the NDK.
3) I will be glad to all kinds of resources where you can read more about such a task.
PS Interested in solutions both on the server and on the client side (although on the client side it would be a little more priority)

Answer 1

There is an open source solution https://github.com/cdcseacave/openMVS that works pretty well.
You need to consider that this task requires a lot of memory and computing resources. You don't have to do this on Android. Rather, it is worth sending data to the server and processing it there. Most of the services (123catch, for example) do just that.
Plus, you need a good camera and the ability to competently shoot frames.
