摘　　要：基于虚拟仪器LabVIEW搭建图像采集系统,实时获取安装在轮胎轮辋上的检测盘边缘图像,并利用图像处理的方法计算出前轮转角信息。试验车进行了静态测试试验,验证了图像处理获取轮胎转向角的测试精度的可靠性,又分别在静态和动态下,进行方向盘转角与前轮转向角对比试验,验证了图像获取前轮转向角的可靠性和稳定性。Based on virtual instrument, called LabVIEW, this article tells us how to build an image acquisition system to acquire real-time edge image on the test plate, which is installed on the tire and rim. And the information of the front wheel angle is calculated with image processing. Static test was conducted on the test car, which verified reliability of image processing for tire test precision of the steering angle. And contrast experiment was carried out on steering wheel angle and front wheel steering angle both in static and dynamic states, which verified the reliability and stability of the image acquisition on the front wheel angle.
