Summary:The present invention provides a method for determining a high-resolution depth map of a scene, the method comprising: obtaining a low-resolution depth map of the scene, obtaining a high-resolution image of the scene, initializing an estimated reflectance map, an estimated lighting vector and an estimated depth map, wherein the estimated depth map is in high-resolution, iteratively simultaneously updating the estimated reflectance map, the estimated lighting vector, and the estimated depth-map, wherein updating the estimated depth map is partially based on the high-resolution image, and determining the high-resolution depth map based on the iteratively updated estimated depth-map.
