Abstract: front page image
(EN)The present invention relates to a method for estimating the surface lapse rate using an infrared image, comprising the steps of: selecting an area to be estimated for estimating the surface lapse rate; calculating the atmospheric transmittance of the area to be estimated; estimating the reference temperature of the reference location arbitrarily set in the area to be estimated; producing an image of the temperature differential by calculating the temperature differential from the atmospheric transmittance and the estimated reference temperature; and estimating the surface lapse rate by means of the distribution of temperature differentials for each elevation from the image of the temperature differential and a digital elevation map (DEM) of the same area. The present invention can estimate the surface lapse rate by means of the correlations of the emissivity and atmospheric effect between surfaces in an image and thus can be utilized in various fields, such as in producing surface lapse rate maps, accurately estimating the changes in temperature due to climate change, observing road hazards in alpine regions, or analyzing the ecosystem in alpine regions.
(FR)La présente invention concerne un procédé pour estimer le gradient de surface à l'aide d'une image infrarouge, qui comprend les étapes consistant à : sélectionner une zone d'estimation, dans laquelle le gradient de surface doit être estimé ; calculer le facteur de transmission atmosphérique de la zone d'estimation; estimer la température de référence de l'emplacement de référence défini arbitrairement dans la zone d'estimation; produire une image du différentiel de température en calculant le différentiel de température à partir du facteur de transmission atmosphérique et de la température de référence estimée ; et estimer le gradient de surface à partir de la distribution des différentiels de température pour chaque altitude à partir de l'image du différentiel de température et d'une carte altimétrique numérique (DEM) de la même zone. La présente invention permet d'estimer le gradient de surface au moyen des corrélations de l'émissivité et de l'effet atmosphérique entre les surfaces dans une image et trouve par conséquent application dans divers domaines tels que la production de cartes de gradients de surfaces, l'estimation précise des changement de températures dus au changements climatiques, l'observation des dangers routiers dans les régions alpines ou l'analyse de l'écosystème dans les régions alpines.
(KO)본 발명은 적외선 영상을 이용한 지표온도감률 추정 방법에 관한 것으로, 본 발명은, 지표온도감률을 추정하기 위한 대상지역을 선정하는 단계; 상기 대상지역의 대기투과율을 계산하는 단계; 상기 대상지역에서 임의로 설정된 기준위치에서의 기준온도를 추정하는 단계; 상기 대기투과율과 상기 추정된 기준온도로부터 온도차를 계산하여 온도차 영상을 제작하는 단계; 및 상기 온도차 영상과 동일 지역의 지형고도자료(DEM; Digital Elevation Map)로부터 고도별 온도차분포를 이용하여 지표온도감률을 추정하는 단계를 포함한다. 본 발명에 의하면, 영상 내 지표간의 복사율과 대기효과의 관계를 이용하여 지표온도감률을 추정함으로써, 지표 온도감율도 제작, 기후변화에 의한 온도변화 정밀추정, 고산지대의 도로위험성 관측, 고산지대 생태계 분석 등과 같은 다양한 분야에 활용될 수 있는 효과가 있다.
