摘要
本文提出了结合状态机与自适应匹配算法来实现停车位检测。首先分析停车位的磁场变化特征,接着提取停车位的磁场变化量,再通过自适应匹配算法来调整阈值。根据实验数据统计,该算法能精确判断停车位状态,且准确率也较高。
In this paper,a combination of state machine and adaptive matching algorithm is proposed to realize parking space detection.Firstly,the magnetic field variation characteristics of parking Spaces are analyzed,then the magnetic field variation of parking Spaces is extracted,and then the threshold value is adjusted by the adaptive matching algorithm.According to the statistics of experimental data,the algorithm can accurately determine the parking space status and has high accuracy.
