Virtual sensor for data and sensor fusion
First Claim
1. A method for classifying an object observed by at least first and second sensors by fusing information from said at least first and second sensors, said method comprising the steps of:
- fusing the response characteristics from the first and second sensors to produce compound sensor response characteristics;
observing an object with said first and second sensors, each of which sensors independently (a) evaluates evidence or information and (b) based on said evidence or information, assigns a taxonomic (type) classification to its observation of said object;
assigning a classification to said object based on said evidence and said compound sensor response characteristics to indicate the type of said object.

Abstract
A plurality of sensors observe an object, and the raw sensor data is processed to produce evidence signals representative of characteristics which may be used to classify the object as to type. The sensor response characteristics from the plurality of sensors are fused to generate fused or combined sensor response characteristics. Thus, the fused or combined sensor response characteristics are equivalent to the sensor response characteristics of a virtual sensor. The evidence and fused sensor response characteristics are applied to a taxonomic classifier to determine the object type.
