摘要: 针对现有套牌车检测方法中所具有的成本高及检测效率低等缺点,提出一种基于历史车牌识别数据(ANPR)集的套牌车并行检测方法TP-Finder,实现了基于整数划分的数据分块策略,能有效求解大规模数据并行处理时的数据倾斜问题,显著提升套牌车辆的发现性能。此外,实现了基于TP-Finder方法的套牌车辆查询系统,可准确呈现所有疑似套牌车辆的历史行车轨迹。最后,在某市真实交通数据集上对TP-Finder方法的性能进行了实验验证。实验结果表明,与缺省的MapReduce 分块策略相比较,TP-Finder的分块策略能够带来最大20%的性能提升。

Abstract: The existing detection approaches for fake plate vehicles have high cost and low efficiency. A new parallel detection approach, called TP-Finder, was proposed based on historical Automatic Number Plate Recognition (ANPR) dataset. To effectively handle the data skew problem emerged in the parallel processing of large-scale dataset, a new data partition strategy based on the idea of integer partition was implemented, which obviously improved the performance of fake plate vehicle detection. Besides, a prototype system for recognizing fake plate vehicles was developed based on the TP-Finder approach, and it could exactly present historical trajectories of all suspicious fake plate vehicles. Finally, the performance of TP-Finder approach was verified on a real ANPR dataset from a city. The experimental results prove that the partition strategy of TP-Finder can achieve a maximum of 20% performance improvement compared with the default MapReduce partition strategy.
