Automated cartographic annotation of digital images
First Claim
Patent Images
1. A method for generating at least one annotated image, comprising the steps of:
- (a) extracting at least one cartographic feature whose visibility from a viewer position of the image has been ascertained, from digital cartographic data representing a map which includes the viewer position;
(b) relating each extracted cartographic feature to a corresponding pictorial feature in the digital image;
(c) annotating at least one pictorial feature based on the corresponding cartographic feature; and
(d) generating the annotated image including each annotated pictorial feature.

Abstract
For annotating a digital image with information from a digital map, features which are visible from a viewer position are extracted from the map. The extracted features are matched with corresponding features in the image, and feature annotations are transferred from the map to the image to obtain an integrated view. The technique facilitates the annotation of photographs, and it can be included in navigation and simulation systems.
