Crowd counting model construction method, counting method and device

Abstract

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 can be improved, a perspective drawing does not need to be used in the training process, and the applicability of the model is improved.

Description

technical field [0001] The invention relates to the field of computer vision, in particular to a method for constructing a crowd counting model, a counting method and a device. Background technique [0002] Crowd counting is to calculate the number of heads from images or video frames, and crowd density is the distribution of crowds in a certain time and space. Accurately estimating the number of crowds and crowd density is one of the important indicators to measure the quality of a security system. Accurately estimating the number and density of crowds plays an extremely important role in public safety and traffic control. At the same time, by analyzing the distribution of crowd density in large shopping malls, customers' purchasing preferences and tendencies can be obtained and potential commercial value can be explored. [0003] In the process of image processing of crowds, the scale change of the characters in the image is difficult to solve by the traditional algorithm...
