Method and apparatus for recovering depth value of depth image

摘要

A method and apparatus for processing a depth image determines a number of mods (NoM) for corresponding pixels in a plurality of depth images. The corresponding pixels may represent a same three-dimensional (3D) point. The NoM may be determined to be a value for minimizing a Markov random field (MRF) energy. A depth value for one depth image may be recovered, and a depth value for another depth image may be updated using the recovered depth value.

1. A method of processing a depth image, the method comprising:
receiving a first depth image and a second depth image, the first depth image indicating an estimated first distance between a first depth camera and an object, and the second depth image indicating an estimated second distance between a second depth camera and the object; determining a number of mods (NoM) of corresponding pixels in the first depth image and the second depth image such that the determined NoM represents a number of periodic phase wrappings in the estimated first distance and the estimated second distance; and recovering a depth value for at least one of the estimated first distance and the estimated second distance based on the determined NoM, wherein the corresponding pixels represent a same three-dimensional (3D) point.
