Description

technical field [0001] The invention belongs to the technical field of detection instruments, and particularly relates to an image measuring device and an automatic focusing method of the image measuring device. Background technique [0002] The development of the manufacturing industry is inseparable from the development of testing equipment and technology. High-quality products not only require high-quality processing equipment, but also depend on the performance of the measuring equipment used. Image measuring equipment is a testing equipment based on machine vision. Usually, an industrial optical lens and a high-resolution charge-coupled device CCD are used to obtain the image of the tested product, and corresponding calculation processing is performed based on the image to obtain the measured value. Dimensional coordinate measurement is the intended application field, and is widely used in machinery, electronics, instrumentation, hardware, plastics and other industries....
