Inventor: HAN JAE HO
IPC: G07C9/00
Filed: 2020-09-07
Abstract: The present invention relates to a disinfection system using a thermal image and a visible image. A camera and a thermal imaging camera are used to double-detect a person having fever and a person not wearing a mask among visitors and simultaneously display warning information to the outside upon occurrence of event, thereby effectively preventing the transmission of infectious diseases such as viruses and bacteria from the outside to maximize heat dissipation efficiency. The image obtained by the camera is analyzed to detect the facial pattern characteristics of the visitor in which facial pattern features, which are pattern features of the upper region centered on the eyes of the face, are detected, and then user authentication is performed by comparing with previously registered registration DBs so that the authentication is possible without the person having to take off the mask separately to perform user authentication, thereby increasing the convenience and efficiency of the certification process, and effectively preventing unnecessary authentication time delays caused by wearing and separating masks. Components such as cameras, thermal imaging cameras, speakers, and LED lights are manufactured as an integrated unit to facilitate the miniaturization and reduce manufacturing and operating costs.
