| 中文摘要: |
| 国内外现有研究工作主要针对车型进行识别，该文在此基础上对车速范围的分类识别进行了研究。文中将主成分分析方法和BP神经网络算法结合(PCA-BP)对车型与车速进行识别分析，对比了与BP神经网络算法识别速度的差异。结果表明应用PCA-BP方法的识别效果整体较好，且在识别过程中可以节省计算时长的50~70%左右，大大提高了识别速度。在未来的车辆识别系统实现中，可以在保证良好识别效果的前提下，提高软硬件平台的传输效率，节省识别计算时间。 |
| 英文摘要: |
| The existed research is mainly related to the vehicle type recognition, the recognition of speed-range of vehicles is proposed in this paper. The paper integrates principal component analysis (PCA) with BP to analyze the recognition of speed-range of vehicles, also compares PCA to BP in differences of recognition-speed. The results demonstrate that PCA-BP method is good, and it boosts speed of recognition by 50%－70%. Thus transmission efficiency of both hardware and software can be improved prominently by this method and also saving recognition time based on good quality of vehicle recognition in the future. |
