Zusammenfassung:To provide a ship imaging system for creating a synthesized image by combining peripheral images of a ship imaged by a plurality of cameras where calibration processing for adjusting ranges in the peripheral images of the ship to be used for the synthesized image is enabled regardless of the ship's location.SOLUTION: A ship imaging system comprises: a plurality of cameras (123f, 13b, 13l, 13r) installed on a ship (101) so as to be apart from one another at predetermined intervals; and a control device (21) for creating a pseudo bird's-eye image (301) by combining peripheral images (Pf, Pb, Pl, Pr) of the ship acquired via imaging by the respective cameras. Adjacent cameras each are installed at a position and angle that cause a portion of the ship to be captured in a shared manner in both of peripheral images by the adjacent cameras. On the basis of calibration indicators (115, 117, 121, 125) provided on portions captured in a shared manner in peripheral images, the control device performs calibration processing of adjusting ranges of the peripheral images to be used for the bird's-eye image.SELECTED DRAWING: Figure 1 【課題】複数のカメラにより撮影した船舶の周辺画像を組み合わせて合成画像を作成する船舶の撮影システムにおいて、船舶の周辺画像における合成画像に用いる範囲を調整する較正処理を船舶が何処にあっても行えるようにする。【解決手段】互いに所定の間隔をあけて船舶(101)に設置される複数のカメラ(123f、13b、13l、13r)と、各カメラの撮影によって取得される船舶の周辺画像(Pf,Pb,Pl,Pr)を組み合わせて疑似の鳥瞰画像(301)を作成する制御装置(21)とを備え、隣り合うカメラは、周辺画像に船舶の一部が共通に写り込む位置および角度に設置され、制御装置は、周辺画像に共通に映り込む船舶の一部に設けられた較正用指標(115,117,121,125)に基づいて、周辺画像における鳥瞰画像に用いる範囲を調整する較正処理を行う。【選択図】図1
