To provide a water area object detection system and a ship and surrounding object detection system capable of creating a water area map (surrounding map) further accurately indicating an object near an image-taking unit.SOLUTION: A water area object detection system 103 is provided in a hull 101 and includes: an image-taking unit 1 which takes an image of the surroundings of the hull 101; and a control unit 3 which detects, based on the image taken by the image-taking unit 1, a feature point F corresponding to an object O in the image together with a distance to the feature point F to thereby perform control of creating a water area map M provided with an object presence range F1, including the possibility that the object O is present, in the surrounding of the feature point F. The control unit 3 is configured to decrease the object presence range F1 with a decrease in the distance from the image-taking unit 1 of the hull 101 to the feature point F corresponding to the object O and also set the size of the object presence range F1 at a lower limit value r1 when the distance from the image-taking unit 1 to the feature point F is equal to or less than a predetermined distance d1.SELECTED DRAWING: Figure 4

    【課題】撮像部の近くの物体をより正確に示す水域マップ(周辺マップ)を作成することが可能な水域物体検出システム、船舶および周辺物体検出システムを提供する。【解決手段】水域物体検出システム103は、船体101に設けられ、船体101の周辺の画像を撮像する撮像部1と、撮像部1により撮像した画像に基づいて、画像内の物体Oに対応する特徴点Fを特徴点Fまでの距離とともに検出することによって、特徴点Fの周囲に、物体Oが存在する可能性を含む物体存在範囲F1を設けた水域マップMを作成する制御を行う制御部3と、を備え、制御部3は、船体101の撮像部1から物体Oに対応する特徴点Fまでの距離が小さくなるにつれて物体存在範囲F1を小さくするとともに、撮像部1から特徴点Fまでの距離が所定距離d1以下の場合には、物体存在範囲F1の大きさを下限値r1に設定するように構成されている。【選択図】図4
