摘　　要：针对城市道路交通,提出了一种基于隐式曲线族的车辆违章检测算法.隐式函数族用于描述道路上的各个不同区域.当检测到车辆在不同道路区域之间行驶时,利用隐式函数族可以快速方便地判断车辆所在区域.根据车辆行驶轨迹和隐式曲线族所描述的不同区域之间的位置关系,能够快速准确地判定车辆是否违章以及所违反的交通规则.在实际检测中,利用分段线性函数族来逼近各个隐式曲线,极大地提高了检测效率,进而提高了违章判断的准确性.实验结果表明,当车辆出现违章时,可以实时显示所违反的具体交通规则.We propose an effective algorithm for the detection of the traffic violation vehicle by employing a set of implicit function curves which can be used to describe the different regions on the roads.When the vehicles are detected to run across different road regions,we can determine in which region that vehicle lies easily and immediately by using the set of implicit functions.According to the vehicle trajectory and the relationship among different regions described by the implicit functions,we can quickly and accurately determine whether the vehicle violates the traffic rules.In order to improve the detection efficiency and accuracy greatly,we use the piecewise linear functions to approximate the set of implicit functions in actual detection.Experimental results show that our algorithm can detect the traffic violation and display the specific violated traffic rules in real time.
