摘要
介绍了一种改进的基于纹理特征的车牌定位方法,采用自适应阈值,实现了车牌的准确定位。设定自适应改变大小的投影切割阈值实现了字符分割。最后采用BP神经网络法来识别各个字符。实验结果表明,该方法能够较为准确的实现车牌识别,具有定位准、鲁棒性好等特点。
The paper introuduces a license plate location algorithm with an adaptive threshold based on an improved texture characteristics for precise location.The feature of character segmentation lies in the projection threshold which is able to change according to different images.Finally BP neural network is used to identify each character.Experimental results show that the method can achieve accurate license plate recognition.
