Apparatus and method for disparity map generation

摘要

A method and system for generating a disparity map. The method comprises the steps of generating a first disparity map based upon a first image and a second image acquired at a first time, acquiring at least a third image and a fourth image at a second time, and determining one or more portions comprising a difference between one of the first and second images and a corresponding one of the third and fourth images. A disparity map update is generated for the one or more determined portions, and a disparity map is generated based upon the third image and the fourth image by combining the disparity map update and the first disparity map.

1. A method for generating a disparity map, comprising the steps of:
generating a first disparity map for images acquired at a first time; determining one or more objects or portions of objects that change position between the images acquired at the first time and images acquired at a second time; generating disparity map update segments corresponding to the objects or portions of objects, wherein a determination of disparity between the images acquired at the second time is performed only on portions thereof that have changed from one or more of the images acquired at the first time; and combining the first disparity map and the disparity map update segments.
