Regional personnel existence detection method

The invention discloses a regional personnel existence detection method. The method comprises the following steps: carrying out image acquisition and radar wave acquisition in a region; establishing a dark channel priority image processing strategy under the condition of weak illumination intensity, and establishing a regional illumination imaging model; defining a dark channel in the image by using any pixel point in the image; extracting the minimum value of the light intensity of the image; establishing a human body vibration model; establishing an adaptive background subtraction equation of index averaging for the radar waves; establishing a radar target enhancement equation; establishing a local energy ratio equation; determining coordinates of the target; according to the method, images and radar application are combined, collected images and radar data are processed through multiple algorithms, whether people exist in an area or not is accurately judged, and compared with a traditional method, the meth
