| 摘 要： | 智能交通系统(ITS),常常要采用传感器对交通目标进行实时定位监控,但被跟踪目标的不确定性以及原始数据通常存在大量噪声的干扰,这对数据融合的精度产生很大的影响.针对这一问题,采用小波变换多尺度分解与重构结合阈值消噪的方法对原始数据进行降噪处理,它能很好的保持原始信号的瞬变特征,并对处理后的数据采用逻辑法进行目标航迹起始...

| Abstract: | In the application of Intelligent Transport System,sensors are often used to locate traffic targets at real-time.However,the target is uncertainty and the raw data usually have a lot of interferences caused by the abnormal data and some other noises.This leads to a great influence to the accuracy of data fusion.Aiming at this problem,wavelet transforming multi-scale decomposition and reconstruction combined with thresholding denoising are used to reduce the orginal noise,which can well maintain the transien... |
