because of different velocity through inductive loop detector, sample ware has flexibility 因为车辆每次经过感应线圈时的速度不同,所以采样波形存在伸缩变化。
the thesis content came from vata ltd . request, which is a vehicle classification system based on inductive loop detectors, made up with data collection sample wave character extracting and automobile type pattern matching . this paper introduces principle of data collection and hardware frame, and examples some common automobile type of data ware at the same time 本文根据优创集团泛安科技开发(石家庄)有限公司关于保定至天津高速公路机电设备更新项目的要求,设计了一种基于感应线圈的车型识别系统,该系统主要由数据采样、采样波形特征提取及车型模式匹配三大部分组成。
