Abstract

The present invention relates to a dual-laser-ranging-based passenger flow direction recognition method and system. The method is as follows: obtaining a first pedestrian characteristic passing through a detecting surface of a laser detection device; obtaining a second pedestrian characteristic passing through the detecting surface of the laser detection device; successively matching entry time and / or departure time, heights, widths and positions in the first pedestrian characteristic and the second pedestrian characteristic, if the entry time and / or departure time, the heights, the widths and the positions all are matched, determining that the first pedestrian characteristic and the second pedestrian characteristic is a same pedestrian; comparing the entry time and / or departure time in the first pedestrian characteristic and the second pedestrian characteristic with one or more time parameter in time for a highest point to pass through the detecting surface, and according to comparison results, recognizing the direction of travel of the pedestrian in a detection channel; and according to the direction of travel of each pedestrian, obtaining the passenger flow direction in the detection channel. The method uses two laser scanning devices ranging without tracing of pedestrians, improves the speed of statistics, and is applied to large passenger flow detection sites.

Description

technical field [0001] The invention relates to the technical field of passenger flow statistics, in particular to a method and system for identifying the direction of passenger flow based on dual laser ranging. Background technique [0002] With the development of the economy, the flow of people has intensified, resulting in traffic congestion, museums, exhibition halls and large-scale event sites and other public places that often have passenger flow congestion during peak hours, and the hazards caused by unexpected situations and unfavorable monitoring of passenger flow status are becoming more and more serious. serious. Therefore, it is necessary to analyze the passenger flow, effectively control the passenger flow density, and prevent the occurrence of public safety incidents such as overcrowding and even trampling injuries. For public transportation systems such as railways, subways, and buses, a detailed grasp of the flow direction, flow time, traffic volume, and dis...
