摘要
Abstract The present disclosure involves generating and hole filling a spherical environment map, comprising: receiving a two-dimensional background image; projecting the background image onto a sphere to generate a sphere image; generating an unfilled environment map containing a hole area based on the sphere image; projecting, using a map projection, a portion of the unfilled environment map to an unfilled projection image; generating a filled projection image by applying a hole filling model to the unfilled projection image, the filled projection image containing image content of the unfilled projection image and image content for the portion of the hole area; projecting, using an inverse projection of the map projection, the filled projection image onto the sphere to generate image content for the hole area of the environment map; and generating a filled environment map by combining the unfilled environment map with the generated image content for the hole area.
