3D Shape Reconstruction Based on Digital Holography of Stereo Matching Techonology
Based on the combination of digital holography and stereo matching technology,a 3D measurement method for 3D shape reconstruction and measurement of digital holography is presented. Firstly, the off-axis Fresnel digital holography system is used, and the single off-axis Fresnel digital hologram of 3D object is obtained. And then,the digital hologram is divided into two parts,two reconstructed images are obtained after the reconsturction,and two reconstructed images exist disparity. At last, the disparity map can be achieved from the matching of two views. Based on geometric relationship, the depth information can be derived from disparity map and used to reconstruct 3D shape of the object. In the experiments,the shape of the scatter and continuous objects are measured by the proposed method, and relative accuracy depth information is derived. The validity of this method is proved by numerical simulation and initial optical experiment.
