Abstract
In this paper, a Kinect based three-dimensional real-life holographic imaging method is proposed. In this method, the three-dimensional information of a real-life scene is acquired by using a commercial Kinect device. The output depth map is converted into a point cloud using the pinhole camera model. Surface reconstruction of the point cloud is achieved by simply using directly uniform sampling method. Our proposed spatial domain Fraunhofer diffraction algorithm is used to generate dynamic hologram videos. Optical reconstruction is performed to test the validity of the proposed method. A universal image quality index is introduced to analyze the quality of holographic imaging. A depth map based triangular refinement method is used to increase the resolution of the 3D model. The final resolution of the reconstructed holographic image can be 3.0 times higher than the original one.
