3D correlation imaging based on gold matrix

In order to improve the quality of 3D image reconstruction, a 3D image reconstruction method based on correlation imaging is proposed by combining the photometric stereo method with the correlation imaging reconstruction algorithm, and the numerical simulation imaging is carried out. A digital projector (DLP) is used as a light source, and four singlepixel detectors placed in different positions are used to collect signals, and a set of 3D correlation imaging experimental system is built to realize the 3D reconstruction of 256pixel*256pixel target objects in the laboratory environment. This paper provides a new method for 3D image reconstruction and a theoretical basis for the practical application of 3D correlation imaging.
