Abstract
A hybrid method for multiple viewpoint projection (MVP) holography using semi-global matching (SGM) and virtual view generation (VVG) is proposed to effectively synthesize a hologram. The stereo correspondence using the SGM method performs much better matching than local methods do and is almost as accurate as global matching methods. The VVG based on the disparity images can generate virtual viewpoint images. This method can conquer the tremendous information of the generated projection images, which improves the process speed and reduces redundant information of the image acquisition process. The method of generating virtual projection images is adopted to avoid applying the camera (or lens) array and the depth camera, so that the image acquisition system complex structure of MVP holography is simplified. The image in-painting method is applied to optimize the virtual projection images and improve synthesis speed and reconstruction image quality. It is possible to acquire and real-time display 3D objects outside the laboratory. In order to challenge the tremendous information of a hologram, several experimental schemes are performed. Experimental results have verified our method validity.
