Abstract

The invention belongs to the technical field of vision measurement, and particularly relates to a multi-axis vision measurement system and a calibration method for the rotation axis position of a pitching table. The measurement system comprises a base, a pitching table, an industrial imaging device, a three-dimensional linear motion mechanism and a calibration block. The three-dimensional linear motion mechanism is installed on the base, the industrial imaging device is installed on the three-dimensional linear motion mechanism, and the industrial imaging device can move in a three-dimensionalenvironment through the three-dimensional linear motion mechanism. The pitching table is installed on the base, and the calibration block is arranged on the pitching table. According to the invention, the space coordinates of the origin of the rotation axis of the pitching table in the machine coordinate system of the multi-axis vision measurement system can be accurately calibrated. The positionof the rotation axis of the pitching table is determined, the measurement precision and the measurement efficiency of parts with complex shapes can be improved, and the measurement system and the method have great practical application value.

Description

technical field [0001] The invention belongs to the technical field of visual measurement, in particular to a multi-axis visual measurement system and a calibration method for the position of the rotation axis of a pitching platform. 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...
