摘要：In the past decades, advances in mechanical engineering have resulted in greater use of vision measurement methods in optical metrology, such as time-of-flight, stereo vision, structured light vision, fringe projection technique, depth from focus, photometric stereo, and digital image correlation. Since the advantages are noncontact, nondestructive, high-precision, automatic, and fast, the vision measurement methods have played an important role in the fields of reverse engineering, online inspection, dimensional analysis, quality assurance, sorting, material handling, and optical gauging. With the rapid development of computer technology and digital image processing technology, more and more vision measurement methods will be applied in many areas of engineering and science.
