摘　　要：公路超限运输是造成公路、桥梁非正常损坏的主要原因。车辆超限重量的增加对公路路面造成的损害程度以几何级数增长,轴载超限使水泥路面使用年限缩短40%左右,使沥青路面使用寿命缩短20%～30%。同时,使载货汽车的制动性和稳定性降低,严重影响行车安全,也会造成国家税费的大量流失。结合对超限车辆的治理工作,提出了可用于车辆外廓尺寸识别的图像标定处理技术方法。该方法是针对车辆外廓尺寸较大,拍摄图片受室外条件影响以及现场车辆查验对计算机图像处理速度的要求而提出的。该方法运算简便,运算速度和精度可达到超限车辆现场查验要求。Today,that transportation capacity of highway is very bigger is the major factor that can make highway and bridge damage.whit the increase of the weight of vehicle,the degree of damage of highway will increase more fast,and the life road surface made of cement will reduce about 40%,that made of pitch will reduce about 20%- 30%. At the same time,the function of brake and stability will be reduced and it is harmful to vehicle safety. This paper puts forward teehnology method of image treatment that can be used to discern vehicle appearance size,combining administration work of vehicle limitation.This method is putted forward because that the size of vehicle is relatively large,the quality of image is influenced by conditions outdoors, and the picture processing speeds of the computer of vehicle checking is required.This method is simple,operation speed and precision can meet the needs of checking.
