摘要
针对隧道监控中的交通参数检测问题,提出了一种基于虚拟检测技术的隧道参数检测方法,挖掘隧道几何模型,定义虚拟线圈和虚拟检测线,根据虚拟线圈感应变化,检测隧道中的车流量;通过拟合投影关系,检测车速,实验结果表明:该方法具有较高检测概率,满足系统的实时要求,并且具有很高的抗噪声干扰能力。
On the basis of the visual detecting technology in digital image processing, a method is proposed to improve the performance in detecting traffic flow parameters of tunnel. Analysing the geometry model of tunnel, visual loops simulating the electronic loops are defined to calculate vehicle number. And visual lines contribute to the calculation of vehicle speed. Higher detection probability, satisfied real-time requirement and resistant ability of noise were proved in the experiences.
