Escalator passenger flow volume statistical method based on video monitoring

Abstract

The invention discloses an escalator passenger flow volume statistical method based on video monitoring. The escalator passenger flow volume statistical method comprises the steps that (1) YOLOv3 is used for conducting head detection on passengers who photograph the escalator at a high angle; 2) training a YOLOv3 network; 3) judging whether the current frame number is a key frame or not, if so, executing the steps 4)-9), otherwise, executing the step 10), and finally executing the steps 11) and 12); 4) detecting the head of the passenger by using YOLOv3; 5) if t is equal to 0, initializing a particle filtering result by using a detection result, otherwise, executing particle filtering; 6) solving a matrix D; 7) performing Hungary matching on the D pair; 8) removing the target leaving the monitoring range; 9) newly adding a target entering the monitoring range; according to the method, the illumination interference resistance is high, the performance is excellent in different illumination scenes, meanwhile, different detection periods can be set according to the conditions of actual equipment, and the accurate passenger flow statistics effect can be achieved on equipment with different properties.

Description

technical field [0001] The invention relates to the technical field of video surveillance and computer vision of an escalator, in particular to a video surveillance-based passenger flow statistics method for an escalator. Background technique [0002] Escalators are usually installed in important places with dense traffic in cities to bring convenience to citizens. Finally, the entrance and exit of the escalator is the "fortress" where the flow of people passes. The statistics of the flow of people at the entrance and exit of the escalator can be used to analyze the passenger flow, so that shopping malls, airports, etc. can make correct decisions in management and decision-making. Therefore, statistics Passenger flow of escalators can assist business analysis and thus bring commercial value. [0003] Traditional passenger flow statistics methods include: artificial statistics, infrared induction, gravity induction, etc. Manual statistical methods are prone to counting erro...
