虚拟线圈数对车流量统计模型影响的定量分析

在定量分析虚拟线圈数目对车流量统计准确率影响因素基础上,采用简化的高斯混合模型进行背景提取,使用背景差法提取出前景信息,经过图像后处理进行车流量统计。最后,基于OpenCV采用C++语言编程实现了求解分析。

This paper aims at quantitative analysis of the influence of the number of virtual loops on the statistical accuracy for vehicle flow. Meanwhile, this paper uses simplified Gaussian mixture model for background extraction, and then uses the background subtraction method to extract the foreground information. After the image post-processing, the vehicle flow is to be calculated. Finally, OpenCV-based C＋＋ language is used to program for solving and analysis algorithm.
