摘　　要：介绍了一种新型的基于层次策略的局部区域检测技术,提取了所有满足候选检测条件的局部兴趣区域。在此基础上,进行梯度增强、冗余边缘去除和车牌分割等精确定位操作。实验结果表明:本文方法对于克服环境噪声具有很强的鲁棒性,实现了高精度的车牌实时定位。A novel search strategy for local region based on hierarchical region detection is proposed.All local regions of interest satisfying candidate detection condition are extracted using this strategy.Then the fine plate location,including gradient enhancement,redundant edge removing and plate segmentation,is performed sequentially.Experiments results show that the proposed method possesses strong robustness to environmental noise and provides high accuracy of real-time license plate location.
