To enable a user to know a location of an on-water object such as a ship in an intermittent manner even in a case where a radar temporarily misses the object.SOLUTION: Direction instruction means 1301 instructs changes in a turning angle and an elevation angle of a camera in such a manner that an imaging direction of the camera is turned towards a location of an on-water object detected by a radar. Image recognition means 1302 recognizes a ship from an image picked up by the camera. The direction instruction means 1301 instructs the changes in the turning angle and the elevation angle of the camera in such a manner that the ship recognized by the image recognition means 1302 becomes closer to a central position in the image. Location identification means 1303 identifies a location of the object on the earth on the basis of the location of the object detected by the radar and identifies the location of the ship on the earth on the basis of the directions of the camera and a distance from the camera to the ship. On the basis of the location identified by the location identification means 1303, discrimination means 1304 discriminates whether the object detected by the radar is a ship that is tracked by the camera.SELECTED DRAWING: Figure 2

    【課題】レーダが船舶等の水上の物体を一時的に見失った場合でも、ユーザが当該物体の位置を継続的に知ることを可能とする。【解決手段】方向指示手段1301は、カメラの撮像方向が、レーダが検知した水上の物体の位置を向くように、カメラの旋回角及び俯仰角の変更を指示する。画像認識手段1302は、カメラが撮像した画像から船舶を認識する。方向指示手段1301は、画像認識手段1302が認識した船舶が画像の中央位置に近づくように、カメラの旋回角及び俯仰角の変更を指示する。位置特定手段1303は、レーダにより検知された物体の位置に基づき当該物体の地球上の位置を特定するとともに、カメラの方向とカメラから船舶までの距離に基づき当該船舶の地球上の位置を特定する。判定手段1304は、位置特定手段1303により特定された位置に基づき、レーダにより検知された物体がカメラにより追尾されている船舶であるか否かを判定する。【選択図】図2
