Underwater object localization using tempalte matching based on DC resistivity method

Underwater object detection and tracking is of great interest for offshore defense. Recently, a new method adopting direct-current resistivity techniques was introduced to complement conventional detection method. The new detection method needs high-speed localization of underwater target object for real-time tracking. In this paper, we propose real-time localization method using grid-based template matching. The templates are generated by numerical modeling in same condition with water tank modeling, and template matching is mainly based on correlation. Localization experiments are carried out using measured data from downscaled water tank to verify proposed method and algorithm. We show results of experiments and confirm the feasibility of this method. We expect that this study will contribute usefully to the algorithm for real-time tracking.
