Abstract

The invention discloses a method for estimating the number of persons based on deep learning, and belongs to the population density estimation based on deep learning. According to the invention, the method comprises the steps: employing a single-column convolution neural network based on a convolution layer and a pooling layer; learning the population features through the training of a large number of samples, estimating the population density map of an input image, carrying out the integration of the density map, and achieving the estimation of the number of persons on the image. Compared with other conventional deep learning algorithm, the convolution neural network employed in the invention is simple in structure, is low in complexity, is short in training time, and is higher in estimation precision.

Description

technical field [0001] The invention belongs to the technical field of digital images, and in particular relates to crowd density estimation based on deep learning. Background technique [0002] With the rapid development of science and technology and the continuous improvement of economic level, people's living needs are getting higher and higher, which has promoted the rapid development of artificial intelligence. At present, artificial intelligence technology has been gradually applied to various fields, including intelligent driving and intelligent monitoring. , security and so on. The estimation of the number of people through video images has important application value in the fields of intelligent monitoring and security. In large public places, such as large-scale event sites, railway stations and other places, the number of people can be estimated in time through images, which is helpful for timely evacuation of overcrowded crowds and prevents stampedes. Wait for t...
