Abstract Accuracy measurement in working space is crucial in the evaluation of machine tools and 3D-CMMs. Though tracking type laser interferometers are widely used in the measurements, there are some problems: The devices are inevitably expensive due to their continuous tracking mechanism; Requiring several hours to measure the entire working space. To solve these problems, A vision-based accuracy measurement system, which utilizes the sequential multi-point method, is developed. The system can measure the entire working space within one hour. The measurement accuracy of the system is equivalent to conventional systems. Verification experiments are conducted on a machining center.

一种基于视觉的机器精度测量方法

摘要 工作空间的精度测量对于机床和 3D-CMM 的评估至关重要。虽然跟踪式激光干涉仪在测量中得到了广泛的应用，但也存在一些问题：由于采用连续跟踪机制，设备价格昂贵；需要几个小时来测量整个工作空间。为了解决这些问题，开发了一种利用顺序多点方法的基于视觉的精度测量系统。该系统可以在一小时内测量整个工作空间。该系统的测量精度与常规系统相当。验证实验在加工中心上进行。
