DETECTING POTENTIAL CHANGED OBJECTS IN IMAGES

摘要

A method of detecting potential changed objects in a first image and a second image, where the first and second images at least partially overlap. The method includes obtaining data describing first and second images and detecting sets of objects in images. A common coordinate system for the sets of objects is calculated. Objects in the sets are eliminated based on positions of the objects and objects outside an area of overlap of the images are eliminated. Data indicating the zero or more remaining objects in the sets is output to indicate potential changed objects.
