Automobile application character is directly affected by the problem of automobile axle base difference between left and right.
汽车左右轴距差问题可直接影响到汽车的使用性能。
In this paper, the tires print images on the condition of automobile straightly running are used to measure the single axle deflection with the method of relative measurement,then the wheelbase difference of automobile is calculated, the experimentation result indicates that the test precision is satisfying.
通过采集汽车直行中轮胎印迹图像 ,利用偏差相对测量法 ,即先测出汽车单轴的偏斜量 ,然后计算出汽车轴距左右差。
