Title:
METHOD OF MOVING TARGET TRACKING AND NUMBER ACCOUNTING
Document Type and Number:
WIPO Patent Application WO/2008/092393
Kind Code:
A1
Abstract:
A method of moving target tracking and number accounting is disclosed. It includes the following steps: a. obtaining a video image including the moving target continuously; b. obtaining the current frame video image, and preprocessing the current frame video image; c. dividing the target region into the preprocessed image, and extracting the target region; d. based on the target region of selecting online feature region, matching the target region of the current frame obtained in the step c, with the target region of the pre-frame, and establishing the matching track chain; and e. determining the target number corresponding to each track chain, according to the target region track recorded by the matched track chain. It can resolve the problem of low- precision of the number accounting results caused by the execrable environment, such as asymmetric distribution of illumination on the space, complicated change on the time and notable pose change etc, in the general application situation.
