  Here, the above-mentioned other ship (not only a small boat but also a wooden ship) is detected by an infrared camera even when the level of a radar reflected wave that can be received is extremely small, By superimposing and displaying on the instruction screen based on the obtained azimuth and distance, it is possible to improve the monitoring ability.

  Furthermore, when the angle of view in the azimuth direction of the image of the other ship captured by the cameras 11-1 to 11-N is 15 degrees, which is much smaller than any of the following, an image of the entire display area Dt is displayed.

(2-2) The above-described oscillation V _{t applied} to the imaging surface of the camera 11-1 according to the components (v _xt , v _yt , v _zt ) is changed to the known distances L ₁ , H, azimuth angle θ _At , By converting based on the camera azimuth angle θ _AC1 and the camera elevation angle θ _EC1 , as shown in FIG. 14, the vertical and horizontal offsets (Δx _{t) of} the area corresponding to the original object field on the imaging surface are obtained. , Δy _t ) and the magnification μ _t that the image in that region should be scaled to give the original image of the scene.

(2-3) The partial image I _PC1t ′ is extracted from the image information I _C1t ′ by removing excess components due to the offset (Δx _t , Δy _t ), and the partial image I _PC1t ′ is changed to μ By performing the map transformation to be multiplied by _t , the original image information I _C1t of the _{object scene} is generated.

Therefore, according to the present embodiment, an image of a desired scene F _CAit (F _CAit ′) can be stably obtained even in a situation where the ship is subject to a wide variety of swings.

  In each of the above-described embodiments, image processing such as sampling, accumulation, extraction, superimposition, and composition is appropriately performed on an image captured by the cameras 11-1 to 11-N located at the highest position on the deck of the ship. As a result, the blind spots of the people on the deck and in the cabin are alleviated and eliminated.

  However, such an image or an image obtained by image processing is associated not only with the relaxation and elimination of the blind spot, but also with, for example, time, ship position, and field of view (azimuth, elevation (decline)). , And may be accumulated as a log that can be used for grasping the background or cause of an accident or event.

  In addition, the detection of a water drop person may be realized more quickly by tracking that is continuously performed from the state in which the target person was present on the deck before the water drop.
