GTA internal camera intrinsic matrix

[Abrar3616]

Hi, how are you? Great work. So i am trying to do a fundamental check on the poses provided by gta and i was wondering if you you could guide me as to how i can get the camera intrinsic matrix. From what i understand about your work, you map an image to 3d world for mapping, correct me if I'm wrong please. What I'm trying to do is kinda opposite. i want to map the 3d pose of game-play camera of gta to an image i got from gta so that i can confirm if the pose provided is correct. If you have extracted the camera intrinsic matrix then could you share it with me or guide me as to how I can extract it correctly myself. Thank you very much in advance.
