摘　　要：基于虚拟线圈的工作原理,将纹理分析技术应用到车辆的视频测速中,采用了基于像素灰度跳变的纹理描绘子作为图像特征和动态阈值做阈值决策的车辆检测算法,提出了一种产生视频触发信号的方法。给出了纹理描绘子和阈值更新的具体算法。经实验,取得了较好效果。Based on the working principle of virtual loops, texture analysis technology was applied to video vehicle detection, with the vehicle detection algorithm that using texture descriptor based on pixel-gray differences and dynamic threshold filter, a method of generating video trigger signals was presented, the specific algorithm of computing texture descriptor and updating threshold was designed. The experiment shows that it is effective.
