System and method for relating a passive sensor to a geographic environment
First Claim
Patent Images
1. A system for relating a passive sensor to a geographic environment, the passive sensor being operable to sense an image of the geographic environment, comprising:
- storage circuitry for storing map data having predetermined levels of complexity to relate with the image and representative of the geographic environment; and
process circuitry coupled to said storage circuitry and to the passive sensor and operable to;
extract at least one image range discontinuity from the image;
generate at least one map range discontinuity from said map data; and
relate said at least one said extracted image range discontinuity to said at least one said generated map range discontinuity with said predetermined levels of complexity, such that the passive sensor is related to the geographic environment.

Abstract
A method and system are provided for relating a passive sensor (14) to a geographic environment (42, 44). The passive sensor (14) senses an image (40) of the geographic environment (42, 44). At least one feature (46) is extracted (26) from the image (40). At least one feature is generated (30) from map data (28) representative of the geographic environment. At least one extracted feature is related (22, 32) to at least one generated feature, such that the passive sensor (14) is related to the geographic environment (42, 44).
