摘要
针对高速公路超限检测,传统方法需要输入车牌信息、疏导交通等人工操作,检测工作耗时耗力,易存在检测误差且高成本等问题,提出基于激光测距的高速公路超限检测方法。该方法首先保证激光测距仪处在高速公路较为稳定的位置,同时将激光测距仪初始化设置,调整激光测距仪的偏角,计算激光测距仪和待检测高速公路物体之间的夹角;然后激光测距仪按照该角度将激光束发射在高速公路上,发生散射现象并产生激光信号,同时采用激光接收器对该激光信号进行接收并读取分析,以此计算出激光测距仪与待检测高速公路物体之间的距离;最终根据该距离可以对高速公路环境进行检测分析,以达到高速公路超限检测的目的。实验仿真证明,所提方法操作过程简洁,超限检测结果较准确,同时节约了检测成本,为高速公路管理工作提供了较有力的依据。
For the highway over-limit detection,the traditional method requires manual operation such as inputting license plate information,diverting traffic,detecting time-consuming and labor-intensive work,easy to exist detection error and high cost,and proposes a highway over-limit detection method based on laser ranging.The method firstly ensures that the laser range finder is at a relatively stable position on the expressway,and at the same time,the laser range finder is initially set,the yaw angle of the laser range finder is adjusted,and the clip between the laser range finder and the object to be detected is calculated.Angle;then the laser range finder emits the laser beam on the highway according to the angle,the scattering phenomenon occurs and the laser signal is generated,and the laser signal is received and read and analyzed by the laser receiver,thereby calculating the laser ranging The distance between the instrument and the object to be detected;finally,according to the distance,the highway environment can be detected and analyzed to achieve the purpose of highway over-limit detection.The experimental simulation proves that the proposed method is easy to operate,the over-limit detection result is more accurate,and the detection cost is saved,which provides a more powerful basis for highway management work.
