Abstract

The invention relates to the image processing technology field and discloses a subway compartment passenger flow statistics method based on video analysis, an apparatus and a system thereof. The subway compartment passenger flow statistics method based on video analysis comprises the following steps of presetting an image acquisition area block and a corresponding detection model; acquiring an image frame group to be detected, wherein the image frame group to be detected includes at least one frame of image; and according to the image acquisition area block and the corresponding detection model, carrying out detection and tracking on the frame image in the image frame group to be detected and acquiring a target track set. In the invention, through carrying out area division on the image frame in the image frame group to be detected, the detection model of a corresponding area is used to carry out target detection and tracking so that a target detection speed is fast and passenger flow statistics precision is high.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method, device and system for counting passengers in subway cars based on video analysis. Background technique [0002] At present, the traditional subway people flow counts the people flow by swiping cards at subway platform gates, counting people by scanning and counting infrared sensors, etc. But it is impossible to count the number of passengers inside a particular subway car in real time. Like the ordinary passenger flow statistics system, the subway passenger density statistics system consists of camera acquisition and video processing modules, network transmission modules, data analysis modules, interaction and display modules. The techniques involved include background modeling, motion detection, object recognition and classification, object tracking, trajectory behavior analysis, etc. [0003] However, due to the particularity of the scene in the sub...
