摘　　要：基于区域跟踪法提出一种视频车辆跟踪系统,改进了系统中涉及的多个方法。以车辆的提取检测结果为基础,提出基于混合差分的车辆检测方法,使检测更快速,检测结果质量更高。通过设计堆栈搜索技术和车辆识别规则,提高了基于差分法的识别准确率,改进了区域跟踪效果。实验结果证明了系统的可行性与实用性。This paper proposes a video tracking system for moving vehicle based on region and several improved techniques of the system. The tracking quality based on region lies on the detecting results. A hybrid difference strategy is introduced to attain higher detecting quality than other methods. A stack searching and a discriminating rule are designed to optimize the vehicle recognition. Experimental results indicate the video tracking system is feasible and useful in application of intelligent transportation system.
