A method and system for monitoring station passenger flow based on building information model

Abstract

The present invention provides a station passenger flow monitoring method based on a building information model, comprising the steps of: S1. Discretize the building information model of the station into a discretized building information model through a plurality of first three-dimensional grids, and convert the discretized building information model into a discretized building information model. A plane building information model, the discretized plane building information model includes a plurality of two-dimensional grids corresponding to the first three-dimensional grid; S2, obtain image information of the station monitoring area through a plurality of image acquisition devices, and discretize through a plurality of second three-dimensional grids Identify the shooting area of ​​the image acquisition device; S3, identify the person in the image information and its position information, assign the person to the corresponding second three-dimensional grid according to the position information, obtain the number of persons assigned to the second three-dimensional grid and map to the corresponding two-dimensional grid; S4, sum up the number of persons in all the two-dimensional grids. The invention also provides a station passenger flow monitoring system based on the building information model.

Description

technical field [0001] The invention relates to the technical field of passenger flow management of rail transit stations, in particular to a method and system for monitoring passenger flow in stations based on a building information model. Background technique [0002] With the acceleration of urbanization in my country and the increase of urban population, urban rail transit has become the main mode of transportation for people to travel in cities. With the rapid development of emerging big cities, the number of young people in cities is increasing, which leads to the impact of rail transit system on commuting to get off work. Various fields have generated great pressure, especially the surge in the flow of passengers entering and leaving and changing passengers at rush-hour stations, which has brought a serious test to the safety management of stations and passenger flow evacuation in urban rail transit. It enables real-time monitoring of station passenger flow and the loc...

Problems solved by technology

[0003] At present, the operation departments of various subway companies have invested a lot of manpower and material resources in the key positions of subway stations, but most of them still use fixed points to disperse the passenger flow, and deploy posts according to the existing operation plan, and lack of response to dynamically changing passenger flow and unexpected situations At the same time, manual observation and station AFC (Automatic FareCollection System) data are still used for passenger flow statistics to carry out fuzzy statistics on passenger flow and personnel density in key areas such as station ticket gates and important entrances and exits, and real-time The reliability is relatively low; large-scale rail transit transfer stations occupy a large area and have many passages in the station, and there is no accurate statistics on the real-time passenger flow information of each specific location in the station

However, while determining the real-time passenger flow through mobile phone signaling, the statistical data is incomplete due to the existence of multiple operators, resulting in a low accuracy rate of passenger flow data.
