(EN) AUTOMATIC OPTIMAL MAPPING METHOD OF REAL IMAGE AND THERMOGRAPHIC IMAGE OF FEVER SCREENING DEVICE AND FEVER SCREENING DEVICE TO WHICH SAME METHOD IS APPLIED
(FR) PROCÉDÉ DE MAPPAGE OPTIMAL AUTOMATIQUE D'UNE IMAGE RÉELLE ET D'UNE IMAGE THERMOGRAPHIQUE D'UN DISPOSITIF DE DÉPISTAGE DE FIÈVRE, ET DISPOSITIF DE DÉPISTAGE DE FIÈVRE AUQUEL LE MÊME PROCÉDÉ EST APPLIQUÉ

Abstract
(EN) The present invention relates to an automatic optimal mapping method of a real image and a thermographic image of a fever screening device, and a fever screening device to which the method is applied, wherein the automatic optimal mapping method applies a frame matching method so that a real image obtained from a real image camera has a wider angle than a thermographic image obtained from a thermographic camera in order to utilize thermographic pixels to the maximum without omission, thereby reconstructing the real image by automatically stretching or shortening the top, bottom, left, and right sides of the real image such that the thermographic image can be utilized to the maximum without omission of thermographic pixels in a fever screening device using an infrared photography device. The fever screening device of the present invention comprises: a thermographic camera which captures a thermographic image of a region including a plurality of subjects; a real image camera which captures a real image of the region including the plurality of subjects simultaneously with the thermographic camera; and an operation processing unit which matches the thermographic image received from the thermographic camera and the real image received from the real image camera, and stretches or shortens the top, bottom, left, and right sides of the real image on the basis of the thermographic image to obtain a reconstructed real image matched with the thermographic image, and detects the body heat (body temperature) of the subjects by using the thermographic image and the reconstructed real image. The fever screening device of the present invention can utilize thermographic pixels to the maximum without omission by obtaining an image of the real image camera that is captured at a wider angle than the thermographic camera, thereby reducing errors and increasing accuracy.
(FR) La présente invention concerne un procédé de mappage optimal automatique d'une image réelle et d'une image thermographique d'un dispositif de dépistage de fièvre, et un dispositif de dépistage de fièvre auquel le procédé est appliqué, le procédé de mappage optimal automatique appliquant un procédé d'appariement de trames de telle sorte qu'une image réelle obtenue à partir d'une caméra d'image réelle possède un angle plus large qu'une image thermographique obtenue à partir d'une caméra thermographique afin d'utiliser des pixels thermographiques au maximum sans omission, ce qui permet de reconstruire l'image réelle en étirant ou en raccourcissant automatiquement les côtés haut, bas, gauche et droit de l'image réelle de telle sorte que l'image thermographique peut être utilisée au maximum sans omission de pixels thermographiques dans un dispositif de dépistage de fièvre utilisant un dispositif de photographie infrarouge. Le dispositif de dépistage de fièvre de la présente invention comprend : une caméra thermographique qui capture une image thermographique d'une région comprenant une pluralité de sujets ; une caméra d'image réelle qui capture une image réelle de la région comprenant la pluralité de sujets simultanément avec la caméra thermographique ; et une unité de traitement d'opération qui met en correspondance l'image thermographique reçue de la caméra thermographique et l'image réelle reçue de la caméra d'image réelle, et étire ou raccourcit les côtés haut, bas, gauche et droit de l'image réelle sur la base de l'image thermographique pour obtenir une image réelle reconstruite correspondant à l'image thermographique, et détecte la chaleur corporelle (température corporelle) des sujets à l'aide de l'image thermographique et de l'image réelle reconstruite. Le dispositif de dépistage de fièvre de la présente invention peut utiliser des pixels thermographiques au maximum sans omission en obtenant une image de la caméra d'image réelle qui est capturée à un angle plus large que la caméra thermographique, ce qui permet de réduire les erreurs et d'augmenter la précision.
(KO) 본 발명은, 열화상 화소의 누락없이 최대로 활용하기 위해 실화상 카메라로부터 얻은 실화상이, 열화상 카메라로부터 얻은 열화상 보다 광각이게 하기 위해, 프레임 매칭 방법을 적용하여, 자동으로 실화상의 상하좌우를 확장(Strech)하거나 축소(Shorten)하여 실화상을 재구성하여, 적외선 촬영장치를 이용한 발열검사기에서 열화상 화소의 누락없이 열화상을 최대로 활용할 수 있는, 발열검사기의 실화상과 열화상의 최적 자동 매핑 방법 및 그 방법을 적용한 발열검사기에 관한 것이다. 본 발명의 발열검사기는, 다수의 피검자를 포함하는 영역의 열화상을 촬영하는 열화상 카메라; 다수의 피검자를 포함하는 영역의 실화상을 촬영하되, 열화상 카메라와 동시에 촬영되는 실화상 카메라; 열화상 카메라로부터 수신된 열화상과, 실화상 카메라로부터 수신된 실화상을 매칭을 행하되, 열화상을 기준으로, 실화상의 상하좌우를 확장하거나 축소하여, 열화상과 맞추어진 재구성 실화상을 구하고, 열화상과 재구성 실화상을 이용하여 피검자들의 체열(체온)을 검출하는, 연산처리부;를 포함하는 것을 특징으로 한다. 본 발명의 발열검사기는, 실화상 카메라의 영상이 열화상 카메라보다 광각으로 촬영된 것을 얻음으로써, 열화상 화소의 누락없이 최대로 활용할 수 있으며, 이로 인해 오류를 줄이고, 정확도를 높일 수 있다.
