提出了一种基于视觉的机床二维定位误差测量方法。在实验中，我们附加一个电荷耦合器件（CCD）相机的主轴，以查看已知的形式精度的工件。利用Sobel算子检测视觉中的边缘，并由此测量出摄像机相对于工件的位置。本文采用蒸镀在玻璃板上的网格作为工件，测量驱动系统的直线度和垂直度。为了比较，我们用涡流位移传感器和方形边缘测量它们。通过使用该测量结果，我们评估这种基于视觉的测量的准确性。
This research presents vision-based measurement of twodimensional positioning errors of machine tools. In experiment, we attach a charge coupled device (CCD) camera to a spindle to view an artifact of the known form accuracy. The edge in the vision is detected by using the Sobel operator and the position of the camera with respect to the artifact is measured from it. In this paper, we use a grid evaporated on a glass plate as an artifact to measure straightness and squareness of the drive system. For comparison, we measure them with an eddy-current displacement sensor and a square edge. By using this measurement result, we evaluate the accuracy of this visionbased measurement.
