Method, Electronic Device, and Storage Medium for Obtaining Depth Image
First Claim
1. A method for obtaining a depth image, comprising:
- mapping a depth image having a first resolution into a color image having a second resolution to obtain a processed image, the first resolution being smaller than the second resolution;
establishing an objective function with respect to the processed image and a depth image having the second resolution, pixels in the processed image having one-to-one correspondence with pixels in the depth image having the second resolution, the objective function aiming to minimize an error with respect to the processed image and the depth image having the second resolution; and
solving the objective function to obtain the depth image having the second resolution.
