I'm quite new to opencv so pardon me if I'm asking a question which is already been answered. I'm trying to find a way do defish an fisheye image (Taken from a gopro). Can someone guide me how i can achieve that, and are intrinsic matrices values required for this purpose? If they are required can i find them for gopro online or do i have to some how calculate them.

If you want to undistort an image you typically need camera calibration parameters. A quite good tutorial can be found here: Link

I don't know if there are any calibration parameters online for a gopro. I think it would be faster to make a calibration on your own since you only require a good chess pattern or similar.
