Abstract

Holographic display is a true three-dimensional (3D) display technology presenting all depth cues without using any special glasses. With this technology we have developed a system of city photonics map. In the system there are three key steps: gaining raw 3D point clouds data, Computer-generated holograms, and digital holographic display of 3D data. In the first step, the theory of structure from motion (SfM) is applied. Then an algorithm of phase CGH with inverse diffraction is proposed and implemented. Difference from ordinary CGH is that the diffraction fringes of 3D reconstructed terrain data are obtained from the diffraction results by the reverse strike means. At last, 3D hologram is displayed on the developing experimental platform and printed on the holographic silver halide plate.
