Lightweight non-contact people number identification method, device and equipment, storage medium and program product

The invention provides a lightweight non-contact people number identification method, device and equipment, a storage medium and a program product. The method comprises the following steps: collecting CSI channel state information data in a scene to be detected; performing optimal antenna pair selection and phase calibration on the acquired CSI channel state information data to obtain amplitude information and phase information; respectively reconstructing the amplitude information and the phase information into a two-dimensional matrix; inputting the reconstructed two-dimensional matrix of the amplitude information and the phase information into an amplitude-phase fusion module, and combining the amplitude information and the phase information; inputting the combined amplitude information and phase information as to-be-fused feature data into a DMConv module for feature fusion; and after feature dimension reduction is performed on the fused feature data by using a global average pooling layer, probability di
