摘　　要：为了解决车辆行驶跑偏测量问题,研制了一种车辆行驶跑偏在线自动检测系统。该系统通过建立的双目机器视觉模型实现了车辆行驶跑偏量的自动测量,研制的大视场激光光源解决了测量中的环境干扰问题,采用优化数据处理算法解决了测量精度不高的难题,构建的无线网络测试系统实现了车辆行驶跑偏在线自动检测。该系统测量精度高、运行稳定可靠,可广泛应用于汽车生产企业及各种车辆检测线上车辆行驶跑偏量的在线自动测量。In order to solve the measurement problem of vehicle driving wandering, an on-line au- tomatic vehicle driving wandering test system was developed. By setting up a binocular vision meas- urement model, the system realized automatic measurement of the vehicle driving wandering quanti- ty. The self-developed wide field of the laser light source solved ambient interference problems when measuring. Data processing algorithm which was optimized solved the problem of lower measurement accuracy. The wireless network test system realized on-line automatic measurement of the vehicle driving wandering. This system has high detection accuracy; it runs stably and reliably. It can be widely used in automatic on-line measurement of vehicle driving wandering quantity in automobile manufacturer and all kinds of vehicle inspection.
