Abstract

The invention discloses population obtaining method, device and system. The population obtaining method comprises the following steps: obtaining a data frame in a monitoring video, setting a target model in the data frame, extracting a foreground image in the data frame, wherein the foreground image comprises a movement target extracted from the data frame; matching the movement target in the foreground image according to the target model, obtaining a population in the corresponding data frame according to a matching result, extracting characteristics of the successfully matched movement target, tracing the corresponding movement target according to the characteristics; obtaining an actual population in the monitoring video within a preset period of time according to a tracing result and the obtained population in each data frame, wherein the tracing result comprises whether the movement target in each data frame is the same movement target. By means of the technical solution of the invention, the efficiency of counting the population and the accuracy of counting can be increased.

Description

Technical field [0001] The present invention relates to the field of computer technology, in particular to a method, device and system for acquiring the number of people. Background technique [0002] In the prior art, the video surveillance system provides basic video surveillance capabilities, and the intelligent video surveillance platform provides platform-side intelligent algorithm analysis capabilities and various intelligent-related business management functions. The intelligent video surveillance platform is one of the existing video surveillance systems. Important function expansion. [0003] As a typical application of intelligent video surveillance, the people counting method based on image analysis has been paid attention to. People counting can play different roles in different applications. For shopping malls, it can be used to count passenger flow and analyze the time and space distribution of passenger flow. As important data, it can improve the staffing of shoppi...
