SYSTEM AND METHOD FOR IDENTIFYING OBJECTS IN AN IMAGE USING POSITIONAL INFORMATION
First Claim
Patent Images
1. A computer-implemented method for identifying objects in an image, comprising:
- capturing an image using a camera;
generating a map that defines a spatial arrangement between objects found proximate to the camera and provides a unique identifier for each object in the map;
detecting objects in the image using feature extraction methods;
identifying the objects detected in the image using the map; and
tagging the objects detected in the image with the corresponding unique identifier for object obtained from the map.

Abstract
A computer-implemented method is provided for identifying objects in an image. The method includes: capturing a series of images of a scene using a camera; receiving a topographical map for the scene that defines distances between objects in the scene; determining distances between objects in the scene from a given image; approximating identities of objects in the given image by comparing the distances between objects as determined from the given image in relation to the distances between objects from the map. The identities of objects can be re-estimated using features of the objects extracted from the other images.
