摘要
载有卫星定位的设备终端是否在设定范围内的检测方法,决定着电子围栏设计的成败。将分类思想用于此类检测,提出一种基于支持向量机的入栏检测算法。该算法依据卫星定位终端的定位数据特征选择合适的核函数;通过网格搜索法求取核函数及误差惩罚参数的值;视检测准确率高低不断调整确定最优阈值等几个环节来实现。用实测数据进行算法验证,入栏检测准确率可达80%~96%,远高于直接检测得到的43%~67%的准确率,表明算法可靠有效,具有较高的实用价值。
The algorithm for detecting whether an equipment terminal with satellite positioning is within the set range or not deserves attention,which is the decisive factor in the design of an electronic fence.An algorithm for entry fence detection based on support vector machine using classification method was proposed.The algorithm mainly consists of three parts:selecting an appropriate kernel function according to the location data of the satellite positioning terminal;calculating the values of kernel function and error penalty parameters through grid searching technique;adjusting threshold value until the detection accuracy is highest.The validity of the algorithm was demonstrated using experimental data from satellite positioning terminals.The detection accuracy rate is estimated to be 80%~96%,which is much higher than the accuracy of 43%~67%obtained by direct detection.The result embodied high practical value for the society.
