| 摘 要： | 车辆通过环形线圈检测器时 ,车体物质与环形线圈相互作用改变了线圈的谐振频率 ,从而形成频率变化曲线。作者采用小波变换方法从频率变化曲线提取车型特征可以实现对车辆的自动分类。分类效果比较理想

| Abstract: | When vehicles passing ring coil detector, the interaction of vehicle body's substance and ring coil changes resonant frequency of the ring coil and forms a curve of frequency variation. The wavelet transformation method is adopted to withdraw vehicle features with the curve and then to assort vehicles automatically. The results of assorting by this method is more successful. |
