Center coordinate calibration method of swing table rotation axis

Abstract

The invention belongs to the technical field of vision measurement, and particularly relates to a center coordinate calibration method of a swing table rotation axis. The calibration method comprisesthe following steps: adjusting a swing table to a first state, and acquiring a first coordinate and a first physical distance of an industrial imaging device in a machine coordinate system O-XYZ; adjusting the swing table to a second state, and acquiring a second coordinate and a second physical distance of the industrial imaging device in the machine coordinate system O-XYZ; and according to thefirst coordinate, the second coordinate, the first physical distance and the second physical distance, carrying out calculating to obtain a central coordinate of the swing table rotation axis. According to the invention, the space coordinates of the origin of the swing table rotation axis in the machine coordinate system of the multi-axis vision measurement system can be accurately calibrated. Theposition of the rotation axis of the swing table is determined, the measurement precision and the measurement efficiency of parts in complex shapes can be improved, and great practical application value is achieved.

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...
