The present invention relates to in detecting black ice by using a temperature deviation generated by a server applying a default emissivity to a thermal image frame of a thermal image photographed by a thermal imaging camera and lowering the emissivity to a set limit value in an arbitrary thermal image frame. Accordingly, in the present invention, black ice is difficult to be determined only with the thermal camera because temperature data of a similar level appears on a road with a low temperature or a road with low temperature. If the default emissivity is applied to the thermal image frame and then the emissivity is lowered to a set limit value in an arbitrary thermal image frame, whether the temperature deviation corresponds to black ice is determined so that the black ice can quickly and easily be detected without many installation equipment.

    본 발명은 열영상카메라가 촬영하는 열영상의 열영상프레임에 대해서 서버가 기본값 방사율을 적용하다가 임의의 열영상프레임에서 방사율을 설정된 극한값으로 낮추어 발생되는 온도편차를 이용하여 블랙아이스를 검출하는 것이다. 이에 따른 본 발명은 온도가 낮은 도로나 온도가 낮아 결빙이 생긴 도로나 비슷한 수준의 온도데이터가 나타나기 때문에 열상카메라만으로 블랙아이스를 판단하기 어렵지만 열영상프레임에 기본값 방사율을 적용하다가 임의의 열영상프레임에 방사율을 설정된 극한값으로 낮추어 온도편차가 블랙아이스에 해당되는지 판단하면 많은 설치 장비 없이 쉽고 빠르게 블랙아이스를 검출할 수 있는 매우 뛰어난 효과가 있다.
