Abstract
A real-world depth map is obtained corresponding to a viewpoint from a perspective of which a virtual-reality (VR) depth map has been generated. For a given pixel in the VR depth map, an optical depth (D) of a corresponding pixel in the real-world depth map is found. A lower bound (D−D1) for the given pixel is determined by subtracting a first predefined value (D1) from the optical depth (D) of the corresponding pixel in the real-world depth map. An upper bound (D+D2) for the given pixel is determined by adding a second predefined value (D2) to the optical depth (D) of the corresponding pixel in the real-world depth map. An optical depth of the given pixel fetched from the VR depth image is re-mapped, from a scale of the lower bound to the upper bound determined for the given pixel to another scale of A to B, wherein A and B are scalars. Re-mapped optical depths of pixels of the VR depth map are then encoded into an encoded depth map. This encoded depth map is sent to at least one display apparatus.
