Embodiment 1

[0088] Sampling 50 scene video picture frames uniformly in time from all scene video picture frames;

[0089] Among the 50 scene video frames, each scene video frame is divided into 4 groups, a total of 200 groups;

[0090] There are temporary IDs of A-H face images in 50 scene video frames, and the temporary IDs of face images are that A and B co-appear in 180 groups of 200 groups, then the synchronization between the two is 180;

[0091] Calculate the synchronicity values ​​of A-B, A-C, A-D, A-E, A-F, A-H, B-C, B-D...B-H, C-D...G-H;

[0092] Divide the final population, and divide A-D into the same group, then the synchronization values ​​of A-B, A-C, A-D, B-C, B-D, and C-D are not lower than the synchronization threshold .

[0093] In this embodiment, each scene video picture frame is divided into groups by the position attribute of the face image, and then the synchronization value of the temporary ID of the face image in each group is calculated, and the group is furth...

Abstract

The invention discloses a people flow conflict adjustment method and system for trajectory prediction, and the method comprises the steps: obtaining a scene video image of a public space, and mining small-scale crowds in the scene video image; generating a people flow track according to the small-scale people flow, and analyzing the operation characteristics of the people flow track; performing similarity analysis on the current crowd and historical crowd records according to the people flow track and the operation characteristics, and generating a prediction result of the crowd flow direction; and early warning pedestrian flow conflicts according to the prediction result of the crowd flow direction, and adjusting the pedestrian flow conflicts. The method can predict pedestrian flow conflicts in advance, dispose and dredge the pedestrian flow conflicts in time, and maintain traffic order and public safety.

Description

technical field [0001] The invention relates to the field of trajectory prediction, in particular to a method and system for regulating human flow conflicts for trajectory prediction. Background technique [0002] Conflicts of people flow may occur in transportation hubs, hot spots of scenic spots and other places, causing congestion, stranded, chaos and other situations, endangering normal traffic order and public safety. In the prior art, only when a conflict of people flow is monitored, the handling and relief can be carried out, and there is a relatively large hysteresis. [0003] Therefore, how to predict crowd conflicts in advance, deal with them in a timely manner, and maintain traffic order and public safety is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] In view of the above problems, the purpose of the present invention is to solve the problem that there is a large lag in the handling and guidance of crowd confli...
