The invention relates to a crowd counting model construction method, counting method and device, and the method comprises the steps: carrying out the head labeling of a crowd image in a pre-stored data set, obtaining a crowd density map, and enabling the crowd image and the crowd density map corresponding to the crowd image to be combined, and obtaining a target data set; performing data amplification processing on a training set obtained by dividing the target data set according to a first preset proportion to obtain a target training set; and finally, training the multi-scale feature aggregation convolutional neural network model after parameter initialization processing by using the training crowd image and the training crowd density map in the target training set to obtain a crowd counting model. By the adoption of the technical scheme, when the model is trained and applied, the problem of scale change of figures in the image can be solved, the calculation amount can be reduced, the recognition efficiency
