Abstract

The invention belongs to the technical field of visual measurement, and in particular relates to a method for calibrating the center coordinates of the rotation axis of a swing table. The calibration method includes: adjusting the swing table to the first state, and obtaining an industrial imaging device in the machine coordinate system O-XYZ The first coordinate and the first physical distance of the first coordinate; the swing table is adjusted to the second state, and obtain the second coordinate and the second physical distance of the industrial imaging device in the machine coordinate system O-XYZ; according to the first coordinate, the second coordinate , the first physical distance and the second physical distance are calculated to obtain the center coordinates of the swing axis of the swing table. The invention can accurately calibrate the space coordinates of the origin of the rotation axis of the swing table in the machine coordinate system of the multi-axis vision measurement system. Determining the position of the axis of rotation of the oscillating table helps to improve the measurement accuracy and efficiency of parts with complex shapes, and has great practical application value.

Description

technical field [0001] The invention belongs to the technical field of visual measurement, and in particular relates to a center coordinate calibration method of a swing axis of a swing table. Background technique [0002] In recent years, with the rapid development of design and manufacturing technology, more and more industrial products and mechanical parts (hereinafter referred to as products) have complex structures, shapes and surface features, which are improving the performance and user experience of products. At the same time, it also increases the difficulty of product processing and testing. In order to ensure the processing quality of products and meet their quality control requirements, accurate and efficient measurement has become a necessary link in the manufacturing process, and the accuracy and efficiency of measurement directly determine the accuracy and efficiency of manufacturing. [0003] At present, it has become an urgent need in the industrial field t...
