The present technology discloses a device for tightly detecting a line switcher. According to a specific embodiment of the present technology, a close spacing between a basic rail and a tongue rail is outputted based on basic rail and tongue rail pixels obtained from a camera installed at a predetermined position on the basic rail, and pixels of a reference object having a fixed value, so that the accuracy of the close contact between the basic rail and the tongue rail is fundamentally improved. In addition, the presence of foreign substances between the basic rail and the tongue rail is diagnosed by using an SSIM value derived through a structural similarity calculation on an acquired image between the basic rail and the tongue rail, so that the adhesion failure of the line switcher due to foreign substances is detected in advance, and accordingly, trains and manpowers are efficiently operated.

    본 기술은 선로전환기의 밀착 감지 장치가 개시된다. 본 기술의 구체적인 예에 따르면, 기본레일의 소정 위치에 설치된 카메라로부터 획득된 기본레일 및 텅레일 픽셀과 고정값을 가지는 기준 사물의 픽셀을 토대로 기본레일과 텅레일 간의 밀착 간격을 도출함에 따라. 기본레일과 텅레일 간의 밀착 간격의 정확도를 근본적으로 향상시킬 수 있다. 또한, 기본레일과 텅레일 사이의 획득된 영상에 대한 구조적 유사도 연산을 통해 도출된 SSIM값으로 기본레일과 텅레일 간의 이물질 여부를 진단함에 따라 이물질로 인한 선로전환기의 밀착 장애를 미연에 감지할 수 있고 이에 열차 운행 및 인력을 효율화할 수 있다.
