[과제] 표지 내용의 식별 정밀도의 향상을 도모하는 것이 가능한 항로 표지 식별 장치를 제공한다. [해결 수단] 항로 표지 식별 장치는, 선박에 설치되는 카메라로부터 부표를 포함하는 제1 화상을 취득하는 제1 취득부와, 제1 화상 내의 부표의 위치를 식별하는 제1 식별부와, 제1 화상 중 부표의 위치를 포함하는 부분 영역에 대응하는, 제1 화상보다 분해능이 높은 제2 화상을 취득하는 제2 취득부와, 제2 화상으로부터 부표의 표지 내용을 식별하는 제2 식별부를 구비한다. The present disclosure provides a navigational sign identifying device capable of improving an accuracy of identifying description of a sign. The navigational sign identifying device includes a first acquirer, a first identifier, a second acquirer, and a second identifier. The first acquirer acquires a first image including a buoy from a camera installed in a ship. The first identifier identifies a position of the buoy inside the first image. The second acquirer acquires a second image corresponding to a partial area of the first image including the position of the buoy, and the second image is higher in resolution than the first image. The second identifier identifies description of a sign of the buoy based on the second image.
