1. A structured-light three-dimensional (3D) scanning system, comprising:
a projector that emits a projected light with a predetermined pattern onto an object;
an image capture device that generates a captured image according to a reflected light reflected from the object, the predetermined pattern of the projected light being distorted due to 3D shape of the object, thereby resulting in a distorted pattern;
a depth decoder that converts the distorted pattern of the captured image into a structured-light depth map representing the 3D shape of the object; and
a depth fusion device that generates a fused depth map according to at least two different structured-light depth maps associated with the object;
wherein the depth fusion device comprises a depth difference device that determines a depth difference between a first depth map and a second depth map at a pixel under determination for accordingly generating the fused depth map, the first depth map being generated by decoding a captured image with a first kernel and the second depth map being generated by decoding a captured image with a second kernel that is different from the first kernel.
