Bus passenger flow statistics method based on multi-motion passenger behavior analysis

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.
