Monocular vision six-dimensional measurement method for high-dynamic large-range arbitrary contouring error of CNC machine tool

A monocular vision six-dimensional measurement method for high-dynamic large-range arbitrary contouring error of a CNC machine tool of the present invention belongs to the field of dynamic error detection of machine tools, and relates to a six-dimensional measurement method for high-dynamic large-range arbitrary contouring error of a CNC machine tool using a monocular vision measurement technology with short-time stroboscopic illumination and a priori standard plate. The method designs a measurement fixture and a measurement system, and uses a monocular vision pose algorithm to improve both the visual measurable dimension and range of interpolated contour in combination with priori knowledge. In light of the principle of error distribution, a small field of view is used to enhance the measurement accuracy of the coded primitives in the images. Then, by traversing all the acquired images using the proposed method, we can obtain the six-dimensional motion contour; and the six-dimensional contouring error caused by the imperfect machine interpolation can be computed by comparing the measured contour with the nominal one. The method enhances the measurable dimension of the vision technology through the monocular vision pose algorithm in combination with a datum transformation method, and realizes the six-dimensional measurement of large-range arbitrary contouring error of the CNC machine tool under the small field of view.
