Abstract

The invention belongs to the field of thermal imaging monitoring, and discloses a thermal imaging monitoring method and a monitoring system thereof. The method includes obtaining an image, and performing fire early warning analysis on the image; the fire early warning analysis includes obtaining the size of the high temperature area and the high temperature area Coefficient, according to the size of the high temperature region, high temperature region coefficient and pixel value of the high temperature region to obtain the regional mean value of the high temperature region, and obtain the average value of the whole map except the high temperature region, and obtain an alarm signal according to the region mean value and the whole map mean value, The high temperature area is an area including the highest temperature position of the image; the method also includes performing head count analysis on the image; the head count analysis includes determining a candidate area of ​​the image according to a head and shoulders template and a threshold value In order to perform primary screening, a classifier is used to perform secondary screening on the candidate area to obtain the number of heads, and the head and shoulder template and the threshold value are constant; the system corresponds to the method.

Description

Technical field [0001] The invention belongs to the field of thermal imaging monitoring, and more specifically, relates to a thermal imaging monitoring method and a monitoring system thereof. Background technique [0002] At present, in crowded places such as movie theaters, game halls and shopping malls, it is necessary to install cameras to monitor abnormal conditions in these places. Currently, the commonly used monitoring equipment mainly includes visible light cameras and infrared cameras. After imaging, the image will be transmitted to the terminal by a dedicated The management personnel can check the abnormal situation in time. [0003] Visible light cameras can obtain better imaging results under good lighting conditions, but it is difficult to guarantee the imaging quality in low-light scenes; infrared cameras can choose infrared lamps with higher power to obtain better imaging quality. Comparison of current applications Extensive, but its service life is short, the cost ...
