METHOD AND APPARATUS FOR GENERATING DEPTH INFORMATION

摘要

A method and an apparatus for generating depth information are provided. A main depth map associated with one of a left image and a right image and corresponding to multiple first pixels is obtained. The left image or the right image associated with the main depth map is divided into multiple segments according to pixel information, so as to obtain a segment distribution map including the segments. Multiple invalid depth values which do not match to a reliable condition are removed from the main depth map according to the segment distribution map, so as to generate a necessary repair depth map including multiple holes. Multiple optimized depth values are respectively generated for the holes in the necessary repair depth map according to the segment distribution map, and the optimized depth values are filled into the necessary repair depth map to generate an optimized depth map.

1. A method for generating depth information, for an electronic apparatus, the method comprising:
obtaining a left image and a right image captured by a stereoscopic imaging system and performing three-dimensional (3D) depth estimation on the left image and the right image so as to obtain a main depth map associated with one of the left image and the right image and corresponding to a plurality of first pixels, wherein the main depth map records a plurality of main depth values respectively corresponding to the first pixels; dividing the left image or the right image associated with the main depth map into a plurality of segments according to pixel information of each of the first pixels, so as to obtain a segment distribution map including the segments; determining whether the main depth values corresponding to the first pixels match a reliable condition according to the segment distribution map and removing a plurality of invalid depth values among the main depth values which do not match the reliable condition from the main depth map, so as to generate a necessary repair depth map including a plurality of holes; and generating a plurality of optimized depth values respectively for the holes in the necessary repair depth map according to the segment distribution map and filling the optimized depth values into the necessary repair depth map to generate an optimized depth map.
