Infrared thermography temperature detection system based on arm rk3568

Thanks to the powerful COVID-19 epidemic prevention and control measures of the Chinese government , The production and life of the people have not been greatly affected . And look around the world , The situation of epidemic prevention and control remains grim , This reminds us that we should not take it lightly , In addition to personal protection , Temperature detection in public places has become a basic but important epidemic prevention and control measure .

The purpose of temperature detection is “ Early screening ”, Find suspected fevers in the crowd in time , So as to further carry out accurate body temperature measurement and follow-up examination .

However, in the mall 、 Station 、 Places with a large flow of people such as hospitals or scenic spots , Manual temperature measurement one by one will appear inefficient and procrastinating , At this time, more efficient and convenient detection methods are particularly important , So we can see 【 Infrared thermography temperature detection system 】 It is being used more and more widely .

【 Infrared thermography temperature detection system 】 Usually by optical system 、 Photodetectors 、 Signal amplification and signal processor 、 The display device and the main control are composed of . With the improvement of epidemic prevention and control requirements and Standards , The requirements for infrared thermal imaging temperature detection system are also getting higher and higher , The accuracy and efficiency of each component must be stronger , Therefore, first of all, it puts forward high requirements for the master control of the system .

Feiling embedded recommendation will FET3568-C The core board acts as 【 Infrared thermography temperature detection system 】 The main control scheme ——FET3568-C Core board based on Rockchip 3568 Processor design and development , Not only have 1TOPS Calculating NPU, There are also rich functional interfaces , Multimedia performance is strong 、 Low power consumption 、 Features of stable operation , Be able to make him perfect for this job .

 FET3568-C Core board Built in image signal processor ISP, And support 1 road DVP and 1 road 4Lanes MIPI-CSI, It can be used to connect infrared camera and visible light camera （ You can also use USB camera ）. Then the infrared detector converts the infrared radiation energy into electrical signals , The input circuit of detector bias and preamplifier outputs the required amplified signal , And transmitted to the readout circuit , For multiplexing .

Four cores 64 position Cortex-A55 framework 、2.0GHz Main frequency 、 And built in 1TOPS Calculate the force NPU Of FET3568-C Core board , Its powerful performance can be achieved by integrating multiple electrical signals D/A While converting and forming standard video signals , Realize the fusion of visible and infrared dual band images , Finally, the real-time temperature measurement and temperature tracking display of the crowd are completed .

  The results of infrared imaging and real-time temperature detection need to be output through the display ,FET3568-C The core board supports HDMI 2.0\eDP\LVDS\RGB Parallel\MIPI-DSI Five display interfaces , Three display signals can be output at the same time , And maximum support 4K The resolution of the , It can make the presentation of the picture clearer , Meet customers' requirements for high image quality .

Besides , You can also use USB or SATA3.0 Connect the external hard disk , Record human flow and temperature information , For later data analysis .
