Embodiment 1
[0029] figure 1 It is a flow chart of the regional people counting method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of counting the number of people in a certain area based on two-dimensional spatial attribute features and cascaded multiple input multiple output (MIMO) radars. This method can be provided by the embodiment of the present invention. The regional people counting device can be implemented, and the device can be implemented by hardware and / or software, and can generally be integrated into computer equipment. Such as figure 1 As shown, it specifically includes the following steps:
[0030] S11. Acquiring radar echo data in a preset area.
[0031] Specifically, the radar radio frequency module can be used to emit electromagnetic waves in the preset area, and the radar echo can be mixed and sent to the AD acquisition module for signal sampling, so as to obtain the radar echo data Y k (n,m), where k represents the ...
