According to the traditional acquisition methods

there is the problem of low accuracy in the acquisition of subway passenger information collection

the proposed intelligent subway passenger information acquisition algorithm based on 3D vision

first using the equipment of CCD digital camera or sensor shooting ZhengZhou subway passenger texture image

to digitize the subway passenger information using three dimensional vision sensing technology

the subway passenger information the data are to the depth of processing noise

threshold segmentation; state space reconstruction and time sequence of subway passenger information

calculating the autocorrelation function of subway passenger information of time series; finally

based on the calculation results of the statistics on the subway passenger information with GPS

wireless communication

subway vehicle tracking and subway card charges intelligent acquisition system

complete the subway passenger information. The experimental results show that the proposed algorithm can greatly improve the efficiency of subway passenger flow information collection

accelerate the speed of information collection

and reduce the cost.
