1. An electronic device comprising:
a processor; and
a non-transitory storage medium coupled to the processor and configured to store a plurality of instructions, which cause the processor to:
obtain first images by a first sensor, wherein the first images comprise depth information;
obtain second images by a second sensor, wherein the second images comprise gradient information, and the first images correspond to the second images;
expand the depth information of the first images according to the depth information of the first images and the gradient information of the second images;
generate third images based on the expanded depth information of the first images;
generating target depth map based on the depth information of the third images and the gradient information of the second images.
