Security check image acquisition method and system based on millimeter-wave radar, and security check equipment

The invention provides a security check image acquisition method based on millimeter-wave radar. The method comprises the following steps of carrying out human existence identification on an originalimage, then carrying out denoising processing on a human image, carrying out statistics based on a grey level histogram to obtain a grey level threshold, carrying out normalization processing on the image based on the grey level threshold, and obtaining the definition of the image through an early-stage training model, thereby obtaining the imaging quality. The invention further provides a security check image acquisition system based on the millimeter-wave radar and security check equipment. The security check image acquisition method and system based on the millimeter-wave radar and the security check equipment provided by the invention have the advantages that whether a human exists is judged based on the grey level value sum, the operation rule is simple, and the accuracy is high; highN-bit data is selected fo
