With the rapid development of industrial Internet, big data, intelligent manufacturing, and artificial intelligence technologies, higher standards are put forward for industrial production, and higher requirements are imposed on the accuracy, flexibility, and reliability of machine tool measurement systems. However, existing measurement technologies have revealed many deficiencies when facing these new challenges.
