Abstract

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. The measurement system includes a base, a pitch 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, and the industrial imaging device is installed on the three-dimensional linear motion mechanism. The three-dimensional linear motion mechanism can realize the displacement of the industrial imaging device in a three-dimensional environment; the tilting platform is installed on the base, and the calibration block is arranged on the tilting platform. The invention can accurately calibrate the space coordinates of the origin of the rotation axis of the pitching platform in the machine coordinate system of the multi-axis vision measurement system. Determining the position of the rotation axis of the pitching platform is helpful 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, 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...
