example

[0057] Example: The infrared image signal output by the infrared detector is converted into a digital signal by a high-speed video A / D (BT835). Simultaneously separated synchronous signal, the memory address of the digital image is produced by the FPGA (EP2C20F256) address generator, like this, the image data in the scope of optional arbitrary size is stored in the image memory (double port RAM). The digital signal processor DSP stores the image in the image memory (dual-port RAM) in the synchronous dynamic memory SDRAM by DMA. The digital processing unit composed of DSP and SDRAM is processing the image data: through the segmentation of the moving target based on the feature object, extracting the edge image of the moving object, calculating the projection function of the edge image and performing area segmentation, the face is determined. Since the video image irradiated by the infrared detector is a black-and-white thermal image with a certain grayscale, the grayscale valu...

Abstract

The invention discloses an epidemic preventing and controlling system for detecting and searching people with abnormal temperatures. The system comprises an information acquisition processing module, a communication processing module and a terminal processing module. The information acquisition processing module consists of an infrared detector, a camera and an information acquisition processor, wherein the infrared detector is used for acquiring face temperature information; the camera is used for acquiring face video information; and the information acquisition processor is used to perform motion target division and profile extraction on the face temperature information and the face video information so as to obtain information of people with abnormal temperatures. The communication processing module is used for transmitting the information of the people with the abnormal temperatures to the terminal processing module. The terminal processing module performs real-time dynamic searching of the people with abnormal temperatures in a monitored area and can send scheduling instruction information for giving an epidemic prompt and tracking people and the like. The system of the invention can monitor and recognize the people with abnormal temperatures in the monitored area and accordingly make a correct response and give good warning for coming epidemics, so that even epidemics outbreak, the people with abnormal temperatures can be found at first time and the epidemic preventing efficiency is improved as high as possible.

Description

technical field [0001] The present invention relates to a prevention and control system applicable to the occurrence of an epidemic, and more particularly, refers to an epidemic prevention and control system for persons with abnormal body temperature by detecting face temperature information and face video information in a monitoring area. Prevention and control system. Background technique [0002] In the face of the sudden outbreak, our country has taken active measures to prevent and control the epidemic. However, despite spending a lot of manpower and material resources, the effect is not ideal, and the disease is still spreading at an alarming rate. The reason, on the one hand, is the strong transmissibility of the disease itself, and on the other hand, it is related to the lack of prevention and monitoring measures in the early stage of the influenza outbreak. [0003] The emergency measures taken by aviation airports in various countries to prevent and control highly...
