Claim 15:
16. A method for fusing depth images, applied to a terminal device comprising a depth camera and an RGB camera, the method comprising:
acquiring a sparse depth image having a resolution of p using the depth camera based on an IToF principle, and acquiring an RGB image having a resolution of a*b using the RGB camera, p being a number of mutually spaced apart speckles of a speckle array that the depth camera is configured to emit, and the RGB image being a two-dimensional image with a and b being numbers of pixels in the two dimensions of the RGB image respectively;
aligning the sparse depth image having the resolution of p with the RGB image having the resolution of a*b; and
fusing the aligned sparse depth image and the RGB image using a pre-trained image fusion model to obtain a dense depth image having a resolution of a*b.
