Abstract

The embodiment of the invention discloses a people counting method and system in an image. The method comprises the following steps: dividing an original image into a distant view area and a close view area; for the distant view area, counting the number of people in the distant view area according to the density map of the human head; for the close view area, counting the number of people in theclose view area according to an object detection network model; and calculating the sum of the number of people in the long-range area and the number of people in the close view area to obtain the number of people in the original image. According to the embodiment of the invention, the method comprises the steps: setting parameters, according to the method, the depth information is used for cutting the distant-view area and the close view area of the image, the areas in the image are reasonably divided, and different methods are used for counting the number of people according to different characteristics of the distant-view area and the close view area, so that the total number of people in the output image is closer to a true value, and the method is particularly suitable for counting the number of people in a complex scene.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a method and system for counting people in an image. Background technique [0002] The monitoring, detection and analysis of crowd activity rules, and the establishment of an automatic, real-time, and intelligent crowd analysis system have extremely important practical significance for building a safe city and a smart city. With the construction of a safe city, a large number of video surveillance equipment has been widely used in public places such as stations, intersections, squares, banks, and supermarkets. The collected video information can be used to effectively monitor and analyze crowd behavior in key places. , can not only provide reusable basic resources for the crowd analysis system, but also visually present visual evidence. [0003] Due to the wide coverage of cameras in special public places, a complex crowd scene appears, which is a random distribution o...
