Problems solved by technology
However, the infrared array is limited by the resolution and detection distance, and auxiliary processing technology is required for target resolution
[0003] The existing indoor population statistics usually use image cameras to collect video information, perform image processing, and use facial recognition technology to count the number of people. This method is limited by image clarity and image processing technology, and the cost is high. Shadow areas, Obstructions are also prone to errors
[0004] How to use infrared technology to reliably realize the analysis of people counting and crowd behavior is an economical method, but its reliability lacks great defects

Embodiment Construction
[0111] The present invention will be further described below in conjunction with the embodiments and accompanying drawings.
[0112] Such as figure 1 As shown, a crowd behavior analysis system based on an infrared array includes a detection terminal 1, a transmission module 2 and a processing background 3, the detection terminal 1 transmits the temperature data packet to the transmission module 2, and the transmission module 2 transmits the temperature The data packet is sent to the processing background 3;
[0113] Such as figure 2 , 7 As shown in ~10, the detection terminal 1 includes an infrared array 102, a controller 101, a wireless communication module 103, and a power module 104. The controller 101 extracts the temperature data collected by the infrared array 102, and the temperature data obtained by the controller 101 The data is packaged into a temperature data packet and then sent to the wireless communication module 103. The power supply module 104 supplies DC p...

The invention relates to a crowd behavior analysis method based on an infrared array-based crowd behavior analysis system. The analysis system is characterized in that it includes a detection terminal, a transmission module and a processing background, and the detection terminal transmits temperature data packets to the transmission module. , the transmission module transmits the temperature data packet to the processing background; the data analysis method based on the analysis system is characterized in that: a people flow behavior analysis system is set, and the analysis method of the people flow behavior analysis system includes human body recognition and flow counting processes, The process of calculating the residence time of people and the process of calculating the flow of people. The beneficial effect of adopting the present invention is that it is convenient to count the number of people in the room in real time, effectively eliminate interference, and reduce statistical errors.
Description
technical field [0001] The invention belongs to the application field of infrared technology, in particular to a crowd behavior analysis method based on an infrared array-based crowd behavior analysis system. Background technique [0002] With the development of modern infrared technology, the application scenarios of using infrared technology to measure human body surface temperature are diverse, mainly divided into indoor scenes and outdoor scenes. The impact of these two scenarios on the application of infrared technology mainly lies in the background of the two There are differences in temperature. One of the key points of distinguishing the application of infrared technology in various fields is to distinguish the target temperature from the background temperature. In order to achieve this distinction, it is usually focused on two aspects of hardware technology and processing technology. Infrared devices using infrared arrays integrate multiple pyroelectric elements, be...
