AUTOMATIC LICENSE PLATE DETECTION IN COMPLEX CONDITIONS OF ACQUISITION

L. A. D'Amore, M. Marengoni

Abstract

The work presented here shows a robust method for license plate detection. The term robust in this work is directly related to the efficiency of the system as an automated locator of license plates without human intervention and considering specific characteristics of image acquisition and license plate features. The proposed method is based on the characters and digits thickness found on the Brazilian license plates. Although the method was designed for the Brazilian license plate pattern it can be easily adjusted to other patterns. The results obtained using the proposed method showed a better performance even when compared to commercial systems.
