Paper money tracking system and method based on machine vision

Abstract

The invention discloses a paper money tracking system and method based on machine vision. The paper money tracking system comprises a camera and a money detector. The camera further comprises an information extraction and analysis system, an engine server, an information management and searching system and a money detector system. When paper money appears in the camera, a wavelet analysis technology is utilized to position a paper money code area where a video frame appears, anti-noise processing is performed on the positioned image area through an AdaBoosting algorithm, the human face is distinguished, a classification algorithm of a soft margin support vector machine is utilized to distinguish codes, and code information serves as a key of paper money flow direction data to be stored in a database. If the fact that someone uses counterfeit money is found, the paper money flow direction data in the database can be called, a user who user the counterfeit money before is tracked, information of the counterfeit money user can also be recorded through the money detector system, and counterfeit money spreading activities can be effectively struck.

Description

technical field [0001] The present invention and a system and method for tracking banknotes based on machine vision. Background technique [0002] In daily life, the use of counterfeit currency directly causes losses to people's interests. After receiving the counterfeit currency, the victim can only admit that he is unlucky and cannot track the user of the counterfeit currency. There is some criminal activity going on at the edge of the ATM. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to provide a machine-based machine that can record the information of each banknote and the person who handles it, so that when a counterfeit banknote is found, the source of the banknote can be found out and the spread of the counterfeit banknote can be prevented directly from the root. Visual banknote tracking system and method. [0004] The present invention is achieved through the following technical solutions: a system and method fo...
