Problems solved by technology

The movement behavior of passengers in the bus is complex and diverse, and some passenger movement behaviors may cause counting interference, misjudgment and missed judgment. Therefore, it is necessary to develop a bus passenger flow statistics method based on the analysis of passenger multi-movement behavior. When counting, fully consider the movement behavior of passengers, make effective counting judgments, and reduce the rate of missed judgments and misjudgments

Embodiment Construction

[0038] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0039] see figure 1 , a bus passenger flow statistics method based on passenger multi-movement behavior analysis, including the following steps:

[0040] 1) see figure 2, the camera 1 is vertically installed directly above the compartment near the bus door to obtain video images of passengers getting on and off the bus;

[0041] 2) Process the video image obtained in step 1), obtain the passenger target by the frame difference method, obtain the target motion area, and then extract the passenger head target by combining the head shape and grayscale features; specifically include the following steps:

[0042] 21) Perform median filtering on the video image obtained in step 1) to reduce the influence of noise on the image;

[0043] 22) Inter-frame difference is performed on the median-filtered video image, that is, the temporally adjacent image frames are differenc...

Abstract

The invention relates to the video image processing and identification technology field, provides a bus passenger flow statistics method based on multi-motion passenger behavior analysis and can settle disadvantages of error judgement and missing judgement existing in a passenger flow statistical method in the prior art during number statistics of passengers in a bus to effectively improve number statistics accuracy of the passengers in the bus. The method comprises steps that: video images of getting-up-and-down passengers are acquired; processing on the acquired images is acquired to extract passenger head targets, and rectangle frames are generated to limit the extracted passenger head targets; matching for centroid points of adjacent frames is carried out in combination with distances of centroid points of the passenger head targets, position information of the centroid points is updated and stored, and each centroid point is connected to acquire a movement locus; locus clustering on the acquired movement locus is carried out to analyze movement behaviors of the passengers; a number statistics result is acquired through counting and determination.

Description

technical field [0001] The invention relates to the technical field of video image processing and recognition, in particular to a method for counting bus passenger flow. Background technique [0002] The number of bus passengers is important bus passenger flow information. Accurate information on the number of bus passengers can assist in the formulation of more scientific dispatching plans. It is the basis for managers to make decisions and the standard for evaluating operation quality. With the rapid development of video image processing and recognition technology, video image processing and recognition technology has gradually been applied to the field of people counting. [0003] The Chinese invention patent application with application number 201210263414.4 discloses a method for counting people based on video image processing. Through target detection, motion area segmentation, and calculation of whether the trajectory of the center point of the sub-area in the monito...
