Abstract
An angle of view calibration method, a virtual reality display system and a computing apparatus are provided. Whether a Head-Mounted-Display (HMD) is worn on the head of a user is detected by a wearing sensor. A current video frame displayed by the HMD is captured in response to the HMD being worn on the head of the user, wherein the current video frame is generated based on an orientation position parameter of the HMD. A frame elevation angle of the current video frame is determined. The orientation position parameter of the HMD is calibrated according to the frame elevation angle, such that the HMD displays a next video frame generated based on the calibrated orientation position parameter.
