Abstract
A hybrid depth estimation system includes a switchable projector that controllably projects either dot light or surface light onto an object; a sensor that receives reflected dot light or reflected surface light from the object to capture a first image or a second image respectively; a dot time-of-flight (ToF) depth generator that generates a dot depth map and an associated dot confidence map according to the first image; a surface ToF depth generator that generates a surface depth map according to the second image; and a denoise processor that processes the surface depth map according to a plurality of points on the dot depth map with high confidence, thereby generating a denoised depth map.
