Personnel access detection method, device and equipment and storage medium

The invention provides a personnel access detection method, device and equipment and a storage medium, and relates to the technical field of digital signal processing. The method comprises the following steps: differencing a real-time temperature image by using a background image to generate a real-time foreground image, and de-noising the real-time foreground image; screening pixel points according to a temperature threshold value, dividing a plurality of pre-selected frames in the real-time foreground image, and adjusting the positions of the pre-selected frames by taking the pixel point with the maximum pixel value in the frames as a new central point; screening by using the score of the pre-selection box to obtain a plurality of target pre-selection boxes, and matching the target pre-selection boxes by using each historical track to generate the latest track of each personnel target; calculating the moving direction of the personnel target according to the current position and the displacement step length
