  • Depth estimation method and depth estimation apparatus of multi-view images
    Patent number: 10573017
    Abstract: A depth estimation method and a depth estimation apparatus of multi-view images where the method includes: taking each image among a plurality of images in a same scenario as a current image to perform the processing of: obtaining an initial depth value of each pixel in the current image; dividing the current image into a plurality of superpixels; obtaining plane parameters of the plurality of superpixels according to a predetermined constraint condition based on the initial depth values; and generating a depth value of each pixel in the superpixels based on the plane parameters of the superpixels; wherein the predetermined constraint condition includes: a co-connection constraint, which is related to a difference between depth values of adjacent points on neighboring superpixels that do not occlude each other.
