Passenger flow monitoring method and system based on multi-data fusion

Abstract

The invention relates to a passenger flow monitoring method and a passenger flow monitoring system based on multi-data fusion. The method comprises the steps: selecting a target region, and presettinga personnel stock initial value in the target region; calculating a first stock estimation Pa according to the number of passengers entering the area and leaving the area obtained by the plurality offlux type counting devices and the initial value of the stock of the passengers, and calculating a first stock estimation error Ea according to the passenger flux and the device error rate; calculating a second stock estimation Pb according to the sum of the number of people acquired by each stock type counting device and the number of people repetition error generated at the device splicing seam, and calculating a second stock estimation error Eb according to the second stock estimation and the device error rate; and according to the first stock estimation Pa, the second stock estimation Pb,the corresponding first stock estimation error Ea and the corresponding second stock estimation error Eb, calculating the comprehensive estimation of the number of people stock and the error range ofthe comprehensive estimation. The method solves the problem that errors exist in current passenger flow monitoring, and the precision cannot meet the requirements of practical application.

Description

technical field [0001] The invention relates to the technical field of passenger flow monitoring, in particular to a method and system for passenger flow monitoring based on multi-data fusion. Background technique [0002] At present, according to the functional classification, passenger flow monitoring terminal equipment can be divided into two types: flux counting equipment and stock counting equipment. Flux type equipment refers to the equipment installed at the entrance and exit of the area to count the number of passengers entering and leaving. This type of equipment has high counting accuracy and stable working performance, but the working area is small, which is not conducive to wide coverage, and the calculation of passenger flow stock The error is affected by the accumulation of flux passenger flow. Inventory equipment refers to the equipment that generally covers the statistical area. This type of equipment has a wide coverage and relatively low cost. There is no ...

Problems solved by technology

Flux type equipment refers to the equipment installed at the entrance and exit of the area to count the number of passengers entering and leaving. This type of equipment has high counting accuracy and stable working performance, but the working area is small, which is not conducive to wide coverage, and the calculation of passenger flow stock The error is affected by the cumulative flow of passengers

Inventory equipment refers to the equipment that generally covers the statistical area. This type of equipment has a wide coverage and relatively low cost. There is no phenomenon that errors will accumulate with the increase of flux, but the accuracy is low, especially in densely populated places. The accuracy cannot meet the actual situation.
