The invention discloses a retention rate statistical method based on human head detection, and belongs to the field of visual target detection and tracking, and the method comprises the steps: obtaining a video image containing a human head; performing target positioning detection on the human head in the video image to obtain a detection frame; performing feature extraction on the detection frame to obtain a target feature, and adding an identity (ID) to the target feature; adding the target features into a tracking list, converting detection information in the tracking list into a retention rate statistical table, and calculating through the statistical table to obtain target detection times; and based on the frame rate of the video image and the target detection frequency, calculating target residence time, setting a time threshold, and based on the target residence time and the time threshold, calculating the residence rate of the target in a certain time period. The technical problem that in the prior ar
