Image Registration for a Camera Array

I have a 2D array of cameras precisely assembled on a grid with equal spacing. There is no rotation between the images. All alignment errors among them can be ignored. It will be used for general purpose imaging, including close-up macros and objects at infinity.

What would be the best approach for image registration among images taken by individual cameras this array? I have seen a huge number of dense articles but can't find anything that gives pro/con comparisons for different usage cases.

Any practical pointers will be greatly appreciated.
