A RAPID INCLINED DISTORTION RECTIFICATION METHOD FOR VEHICLE LICENSES PLATE IMAGES

摘要：

The inclined distortion is the crucial problem that influences the procession for the vehicle licenses plate image recognition. However, as a result of the inclined distortion, the vanishing points provide valuable information concerning the camera model used to capture the image. In this paper, a robust and fast algorithm for inclined distortion correction in vehicle licenses plate images based on vanishing points is put forward. This method includes three steps: detecting vanishing points in an image, calibrating camera model coefficients and correcting inclined distortion. Experimental results show this method performs well and increases the recognition rate.
