摘要
基于近景摄影测量对图像滤波除噪、图像分割、特征提取等图像处理过程进行分析,并利用VB6.0为软件开发平台,实现了基于近景摄影视频采集的车辆轨迹提取功能。最后以东直路路段为例,运用软件实现了对车辆行驶轨迹的提取,并勾勒出了速度变化曲线图。
The Process of picture filter except chirp, the picture division, the characteristic withdraws question based on Close Range Photogrammetry are analysed. And it uses VB6. 0 as the software development plat- form, realizes has withdrawn the function based on the video frequency gathering vehicles path. At last, the Dong- zhi road section for example is taken, and realized using software to vehicles travel path withdrawing.
