Abstract：With the rapid development of the Internet of Things technology, many intelligent scenarios such as personalized heating and cooling, natural light adjustment, energy distribution, health and safety, etc. have huge application potential.As the final consumer of this kind of intelligent scene, the perception and detection of "people" and further real-time quantity statistics are particularly important.This topic is mainly aimed at people entering and exiting the entrance and exit areas of the home environment, using 60GHz millimeter wave radar, based on the group tracking algorithm combined with the newly proposed regional personnel statistics algorithm, a design and implementation Personnel detection and statistics system.The calculation process of all algorithms in the system is located in the radar chip, and does not need additional remote (PC, Server) computing power support.The final experimental results show that when personnel enter in turn, the comprehensive accuracy of detection and statistics of the system is 97%; When personnel enter in parallel (in extreme cases), the comprehensive accuracy of detection and statistics of the system is 91%.
