Abstract

The automated vehicle license-plate locating, is an important part in the intelligence traffic system. It is a key step in the Vehicle License Plate Recognition (LPR). A method for the recognition of images of different backgrounds and different illuminations is proposed. The gray beep points of the row is used to get the horizontal projection of the image first. Then the edge characteristic of the image line is used to get the vertical projection and locate the vehicle license plate. Theoretical analyses and experimental results show that the method is quite effective, which is excellent in accuracy, robust and valuable in practical application.
