With the rapid development of science and technology today, three-dimensional information has gradually become a means for human beings to understand and transform the world. As a 3D reconstruction method with a wide range of applications and deep theoretical research, structured light has always been a research hotspot. The structured light system pursues high precision, high efficiency and low cost, so the team proposed efficient and robust improved algorithms for the calibration method, pattern coding, and phase unwrapping in the measurement of the structured light system. For the reconstruction of structured light in special environments, the team proposed solutions for highly reflective parts and specularly reflective objects. It is of great significance to the industrialization of factories. The research results have great development prospects and usefulness in industrial testing and consumer entertainment.
