Omni-Directional Surveillance for Unmanned Water Vehicles
Abstract
This paper proposes a framework for automatic maritime visual surveillance using an unmanned water vehicle (UWV). The UWV is equipped with a GPS, an e-compass and a high resolution omni-camera. A fast algorithm is proposed to automatically calibrate the moving omni-camera in real time. Moreover, a saliency based visual attention method is used for target detection. Targets are tracked using adaptively selected discriminative features and mean shift. Target locations are then geo-registered to a map, and displayed on a situational awareness console. Experiments on real data in a system deployment demonstrate the effectiveness of the maritime surveillance framework.
