[Problem] To provide a route sign recognition device capable of discriminating a port sign and a starboard sign regardless of the position of a ship. [Solution] A route sign recognition device is provided with: an acquisition unit for acquiring an image generated by a camera provided on a ship; a form recognition unit that recognizes whether the form of the side buoy included in the image is a first form or a second form; a country determination unit that determines a country to which the position detected by the position detection unit that detects the position of the ship belongs; and a port/starboard determination unit that determines whether the identification content of the side buoy is the port identification or the starboard identification from the form of the side buoy and the determined country on the basis of a prescribed correspondence relationship indicating whether the first form and the second form correspond to the port identification or the starboard identification in each country.
【课题】提供一种不依赖于船舶的位置而能够判别左舷标识和右舷标识的航路标识识别装置。【解决手段】航路标识识别装置具有:获取部,获取由设置于船舶的摄像头生成的图像;形态识别部,识别图像中包含的侧面浮标的形态是第一形态和第二形态中的哪一个;国家判定部,判定由检测船舶的位置的位置检测部检测的位置所属的国家;以及左右舷判定部,基于表示第一形态和第二形态在各国中对应于左舷标识和右舷标识中的哪一个的规定的对应关系,从侧面浮标的形态和判定出的国家来判定侧面浮标的标识内容是左舷标识和右舷标识中的哪一个。
