Pedestrian tracking and counting method and device for near-front top-view monitoring video
First Claim
1. A pedestrian tracking and counting method for a near-front top-view monitoring video, comprising:
- acquiring a video image under a current monitoring scene;
comparing the video image with a background image, and when it is determined that the video image is a foreground image, segmenting and combining each blob in the foreground image to acquire a target blob representing an individual pedestrian;
performing tracking and counting according to a centre-of-mass coordinate of each target blob in a detection area to acquire the number of pedestrians under the current monitoring scene.

Abstract
Provided are a pedestrian tracking and counting method and device for a near-front top-view monitoring video, wherein the method includes that a video image under a current monitoring scene is acquired, the acquired video image is compared with a background image, and when it is determined that the video image is a foreground image, each blob in the foreground image is segmented and combined to acquire a target blob representing an individual pedestrian, and tracking and counting are performed according to the centre-of-mass coordinate of each target blob in a detection area to acquire the number of pedestrians under the current monitoring scene. Thus the accuracy of a counting result can be improved.
