Features: Industrial measurement is a discipline that provides measurement technology support for various stages of industrial production and scientific research, including product design, simulation, measurement, layout, replication, simulation, product quality control, and product motion state. Measurement primarily focuses on the geometric dimensions of products but also involves color, temperature, speed, acceleration, and other physical quantities. The measurement environment is mostly indoor, specifically in factory workshops or research laboratories, often accompanied by high-precision and high-frequency requirements. Of course, the measurement of outdoor industrial targets is also an important aspect that cannot be ignored. The rapid development of modern industrial technology has provided numerous measurement techniques and methods for industrial measurement; similarly, the rapid development of modern industrial technology also requires the support of industrial measurement technology. Industrial measurement is an indispensable important production link in modern industrial production. With the development of industry, there are a wide variety of means or instruments available for industrial measurement, such as:
1D, 2D, and 3D mechanical measurement tools or equipment, various specialized 1D sensors based on optoelectromechanical technology, various instruments and equipment based on angle measurement, various optoelectronic distance measurement instruments based on distance measurement, camera equipment and photogrammetry systems based on various solid-state cameras, various specialized 1D, 2D, and 3D industrial photogrammetry systems, optical microscopic imaging measurement systems, electronic microscopic imaging measurement systems, 1D, 2D, and 3D photogrammetry systems based on high-speed imaging, industrial measurement systems based on Moire fringes, measurement systems based on the principle of optical wave interference, 3D measurement systems based on magnetic fields, industrial measurement or industrial imaging measurement systems based on structured light, Motography automatic measurement technology, and even global positioning systems for measuring the trajectories of airborne objects. This work covers many aspects of static and dynamic industrial target measurement, involving various means of industrial measurement, and encompasses numerous aspects of measurement theory, methods, and processes. Focusing on non-contact measurement methods, this book can be applied to education, production, and research in industrial measurement, serving as a reference for students and teachers in surveying and mapping disciplines, as well as for scientific and production personnel in various industrial fields. This book includes some unique theories and methods developed by us, such as: the scanning mathematical model and its application of a laser theodolite with three rotational degrees of freedom, the classification and selection principles of industrial measurement methods, the establishment of modular 3D industrial measurement systems, the establishment of high-precision, on-site, industrial control networks in workshops, the principles and methods of batch large-scale industrial component inspection and layout, the establishment of digital distortion models, the hole group positioning and CNC drilling based on digital cameras, the particularity of industrial photogrammetry tolerance, the general form of error equations based on collinearity condition equations, a new theory of digital rectification with a minimum number of control points, and the integration technology of industrial measurement sensors, etc.
