I bought a 360 degree camera and I want to calibrate it. I know that video and images taken by 360 degree camera has metadata in the files taken.

In this metadata it is stored the camera parameters, like the matrix camera?

"360 degree camera" -- what does this mean, exactly ?

unfortunately, opencv does not have any means to read metadata from images, if there's something interesting for the calibration in it, you'll have to rely on an external tool.

With "360 degree camera" I refer to camera that take a picture with 2 cameras and it can record all space around it, like this:

ok. that's called "dual fisheye", btw. if you cannot retrieve calibration data from the manual, or the image-metadata, you might try to calibrate both of them manually using fisheye or omni calibration

Ok, but the camera takes images (or videos) with 2 images (or 2 videos) in the same file (like this: Do I need select a roi with only one image (or only one video)?

yes, i think you need to select the roi of each cam, and process those seperately.
