People flow statistical system and people flow statistical method

Abstract

The invention provides a people flow statistical system and a people flow statistical method based on video image analysis. The people flow statistical system comprises a single-image photographing unit, a speed estimating unit, a puzzle generating unit and a decision model unit, wherein the single-image photographing unit is placed just above a detection line and used for photographing a video image of the top of a pedestrian from top to bottom; the speed estimating unit is used for calculating speed information when each pedestrian passes through the detection line in the video image by using the optical flow method; the puzzle generating unit is used for calculating the distance that the pedestrian passes through the detection line in each video image according to the speed information, taking the distance as the slicing thickness, and restoring the whole puzzle of the pedestrian by continuously accumulating slices; the decision model unit is used for analyzing by utilizing linear regression according to the puzzle restored by the puzzle generating unit, calculating the number of pixels and the number of edge information in the puzzle, and counting the number of people in the puzzle. Compared with the prior art, the system and the method have the advantages that the problem that pedestrians keep out each other can be avoided, and are beneficial to improving the counting accuracy when people is crowded.

Description

technical field [0001] The invention relates to people counting technology, in particular to a people counting system and method based on video image analysis. Background technique [0002] In many industries, people flow information can provide a key basis for people flow management, resource management, and management decisions. For example, in subway stations, pedestrian counting can be used to understand the size of the flow of people at each station in real time, flexibly schedule the density of subway trains, implement flow control, and release information on densely populated areas in real time, which is conducive to enhancing the efficiency of crowd transportation and ensuring smooth and effective subway operations. In a shopping mall, the flow of people is an important basis for reflecting its commercial value. Accurate calculation of the flow of people is conducive to grasping the shopping preferences of customers, so as to achieve better logistics arrangements, an...
