US 7,117,192 B2 · Text and imagery spatial correlator

Abstract

A text and imagery spatial correlator automatically relates the geographic locations where events referenced in text occur to those same geographic locations appearing in imagery. In the preferred embodiment, the system deploys adaptable, context-sensitive agents for the automatic interpretation of text, and the application of those agents to classify and geolocate textual references. The results are integrated with similar spatial references from imagery in a common data model, accessible by both spatial and non-spatial data correlation. The unique combination of elements enables the system to automatically develop spatial relationships between text and imagery. Although the invention finds utility in numerous applications, the system and method are particularly useful in correlating remote sensor imagery.

Dependent claims

A method of correlating text and imagery, comprising the steps of:

specifying a target concept;
providing textual material and imagery;
training a text search detector to examine the textual material for text regions which relate to the target concept, and creating a text target detection record in a database A in the event of a match or other meaningful association;
training a discriminating feature detector to search for locations within the imagery which relate to the target concept, and creating a location target detection record in a database B in the event of a match or other meaningful association;
and
comparing the records in both databases to declare an approximate correlation, if any, indicative of a common target concept.
