Interpretation and Fusion of Sonar Images Using Evidential Reasoning
Abstract
In mine warfare classification of bottom objects is essential. It is also one of the major problems. Especially when there is considerable sea-bottom clutter as in many MCM situations. This report presents a novel approach to automatic interpretation of sonar images of the sea-bottom, which allows combination of information from multiple images of the same site.The method provides increased reliability in the interpretation compared to existing methods, as information from several images is utilized. Additionally, a distinction is made between uncertainty and ignorance. This distinction is relevant as imprecision in an interpretation of a sonar image can be due to both ambiguity and to lack of knowledge. The viability of the technique is demonstrated by combining sonar images acquired with an experimental sonar with two simultaneous views.
