Description

합성 영상을 이용한 화재감지시스템 및 방법Fire detection system and method using composite image
본 발명은 합성 영상을 이용한 화재감지시스템 및 방법에 관한 것으로서, 더욱 상세하게는 영상 카메라로 촬영된 실제영상과 온도변화에 따른 열영상을 합성하여 불꽃이 없는 상황에서도 열 영상을 통한 객체의 온도변화를 감지하여 잠열을 확인할 수 있는 합성 영상을 이용한 화재감지시스템 및 방법에 관한 것이다. The present invention relates to a fire detection system and method using a composite image, and more particularly, to synthesize a thermal image according to a temperature change and a real image photographed with a video camera to change the temperature of an object through a thermal image even in a flameless situation. It relates to a fire detection system and method using a composite image that can detect the latent heat by detecting the.
통상의 소방관리에 사용되는 화재감지기는 화재를 감지하여 화재신호를 직간접적으로 관리자 또는 소방관제센터로 화재경보를 한다. 이때, 화재신호에 따라 자동으로 옥내외의 소화설비인 스프링클러를 제어하여 화재를 진압한다.The fire detector used for normal fire control detects a fire and sends a fire signal directly or indirectly to a manager or fire control center. At this time, according to the fire signal to control the sprinkler which is the fire extinguishing equipment indoors and outdoors, extinguish the fire.
이러한 일반적인 화재감지기는 소방시설이 설치된 건물의 내외에 다수의 수신기가 설치되어 있더라도, 이들 화재감지기간에 상호통신이 불가능하여 건물이용자에게 신속한 화재정보를 전달할 수 없고, 특히 화재의 최초 발생시간 및 발생장소가 전달되지 않는 문제점이 있다.Such a general fire detector, even if a plurality of receivers are installed inside and outside the building in which the fire facilities are installed, cannot communicate with each other during the fire detection period, and thus can not quickly transmit the fire information to the building user. There is a problem that the place is not delivered.
또한, 일반적인 화재감지기는 화재감지 및 화재를 알리는 것에 국한되어 있고, 다른 시스템과 유기적으로 결합하여 상호적으로 작용하기 어려운 문제점도 있다.In addition, the general fire detector is limited to the fire detection and the notification of the fire, there is also a problem that it is difficult to interact with other systems organically combined.
또한, 각 지역의 소방관서에서는 119 지령실 및 관제센터를 운영하면서 화재신고 또는 화재 인식시 GPS, GIS 등을 이용하여 화재발생 위치 및 주변 정보는 인지할 수 있으나, 현재 화재 상황에 대해서는 실시간 감지할 수 있는 시스템이 없다.In addition, fire departments in each region operate the 119 command room and control center to recognize the location of fire and surrounding information using GPS and GIS when reporting a fire or recognizing a fire, but can detect the current fire situation in real time. There is no system.
따라서 종래에는 특허등록 제1175202호(2012.08.13 등록)를 통하여 실시간으로 화재를 감지 및 모니터링 할 수 있는 시스템이 제안되었다. 하지만 상기 종래기술은 불꽃과 연기가 발생됨을 감지하여 화재를 감지하는 것으로서 불꽃과 연기가 발생되지 않더라도 온도가 높은 상태인 잠열 상태에 따른 화재가능성 여부를 감지할 수 없었다. Therefore, in the related art, a system capable of detecting and monitoring a fire in real time through a patent registration No. 11175202 (registered on August 13, 2012) has been proposed. However, the prior art is to detect the fire by detecting the occurrence of the flame and smoke, even if the flame and smoke does not occur, it was not possible to detect the possibility of fire according to the latent heat state of high temperature.
즉, 종래의 화재감지기술은 온도의 상승과 연기 및 불꽃을 감지해야만 화재를 경보하는 것으로서 화재 가능성이 높은 잠열의 감지장치나 방법이 전무하여 화재를 미연에 방지할 수 없는 문제점이 있었다. That is, the conventional fire detection technology has a problem that can not prevent the fire in advance because there is no detection device or method of latent heat that is likely to fire as a fire alarm only when the temperature rise and the smoke and the flame is detected.
또한 종래에는 센서나 영상을 통하여 화재를 감지 및 경보하는 기술이 주를 이루었었다. 하지만 이와 같은 종래의 화재감지 및 경보장지에서 영상을 통한 화재감지장치는 빨간색의 의상이나 벽지를 화재로 인식하거나, 또는 음식의 조리과정에서 발생되는 연기를 화재발생에 따른 연기로 인식하기 때문에 정확도가 매우 낮은 문제점이 있었다. In addition, conventional techniques for detecting and alarming the fire through the sensor or the image was the main. However, in the conventional fire detection and warning device, the fire detection device using the image recognizes the red clothes or the wallpaper as a fire, or the smoke generated during the cooking of food as the smoke caused by the fire. There was a very low problem.
따라서 본 발명은 상기와 같은 종래의 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 실영상 카메라로 촬영한 실영상과, 열상카메라를 통하여 촬영된 열영상을 혼합하여 불꽃이나 연기가 발생하지 않더라도 온도의 변화를 감지하여 화재 발생 가능성을 감지할 수 있는 합성 영상을 이용한 화재감지시스템 및 방법을 제공함에 있다. Therefore, the present invention has been made to solve the above-mentioned conventional problems, an object of the present invention is to mix a real image taken with a real image camera, and a thermal image taken through a thermal camera does not generate flame or smoke The present invention provides a fire detection system and method using a composite image that can detect a change in temperature even if a fire occurs.
본 발명은 불꽃이나 연기가 발생하지 않더라도 온도의 변화를 감지하여 화재 발생가능성을 정확히 감지하기 위하여 다 수개가 설정된 구역내에 각각 설치되어 해당 구역의 실제 영상과 온도에 따라서 서로 다른 색상으로 표시되는 열영상을 혼합한 합성 영상에 포함된 다 수개의 객체를 분리하여 상기 객체중에 불꽃 및 연기가 포함되었는지를 분석하여 경보를 발령하는 것을 특징으로 한다. In the present invention, even if no flame or smoke is generated, in order to detect a change in temperature and accurately detect the possibility of a fire, the thermal images are installed in different colors and displayed in different colors according to the actual image and temperature of the corresponding zone. It is characterized by separating a plurality of objects included in the composite image mixed with and analyzing the flame and smoke contained in the object to issue an alarm.
본 발명은 상술한 바와 같이 실영상 카메라에서 촬영된 실영상과 열영상 카메라를 통하여 촬영된 열영상을 혼합하여 객체의 잠열을 확인할 수 있기에 화재의 발생 및 화재의 발생 가능성을 감지 및 경보할 수 있는 효과가 있다. According to the present invention, since the latent heat of the object can be checked by mixing the real image photographed by the real image camera and the thermal image photographed by the thermal image camera as described above, the occurrence of a fire and the possibility of occurrence of a fire can be detected and alarmed. It works.

Referring to FIG. 3, the fire detection method using the composite image according to the present invention synthesizes and converts an image captured by the real image camera 111 and the thermal image camera 112, and transmits the image to the image server 30. In step S10, the object recognition step (S20) for recognizing the flame and smoke by separating each object included in the composite image of the image processing step (S10), and the flame and smoke in the object recognition step (S20) Is detected, the sensor interlocking step (S30) and the sensor interlocking step (S30) in conjunction with the detection signal of the sensor to determine the possibility of fire, and if the fire occurrence or fire occurrence is determined as one of the possibility of fire in the sensor interlocking step (S30) Alert and communication step (S40) for transmitting a possible alarm.
