Image measuring instrument is a high-precision measuring instrument that adopts new image measurement technology, mainly developed to meet the needs of users for rapid measurement. It can measure two-dimensional plane dimensions with one click and three-dimensional point laser height measurement, achieving precise and fast measurement of height dimensions, flatness and other parameters. In the field of industrial manufacturing, it can improve the efficiency of production lines and product quality by accurately measuring target objects, and is widely used in product quality control and process improvement.
