The invention discloses a population counting method based on (a) scale-adapted head detection and density map. Characteristic training and prediction are carried out on an image; gradient informationand a foreground are extracted from the image; the scale and parameters corresponding to the image are generated; a foreground image is segmented, samples are screened; a training model of the head is obtained by training the samples; a training model is used to implement prediction, and a prediction result is obtained; and multiple scales of density maps are generated according to the predictionresult, and the density maps are added to obtain the total prediction number. Pedestrians in the image are counted by combining scale-adapted method with head detection, and the disadvantage in perspective transformation of a common detection method is overcome; and the adaptive scale screening method and the density map are used to obtain a higher robustness of the method, and the method can beapplied to different scenes
