摘要: 为了提高超限运输检测的精度, 提出了车辆装载几何参数超限识别方法。应用2个激光测距传感器分别扫描通过车辆, 得到不完整的端部轮廓以及各点坐标值, 根据左轮廓最小横坐标、右轮廓最大横坐标与两轮廓的最小纵坐标, 计算了车辆装载宽度和高度, 再经过轮廓合成, 得到完整的正投影, 应用光幕和光电开关构成的复合基准点判定装载长度, 并与载货汽车运输超限判定标准比较。现场测试结果表明: 检测误差在±3%的范围内, 可以实时存储通过车辆身份, 因此, 识别方法精度较高, 检测结果直观。Abstract: In order to improve the precision of inspecting oversize transportation, identifying method of geometry parameters for oversize vehicle was proposed. Vehicle was scanned by using two laser measurement sensors respectively to acquire the half outlines of vehicle and the coordinates of all inspecting points, the height and width of vehicle were computed according to the minimum abscissa of left outline, the maximal abscissa of right outline and the minimum ordinate of two outlines, the whole outline of vehicle was gained by using outline synthetic method, vehicle length was identified according to the datum marks consisted of light curtain and light-electricity switch and was compared with the standard of oversize transportation. Computation result shows that inspecting error is within ±3%, vehicle license is stored in time, so the precision of the method is higher, and inspecting result is intuitionistic.
