【摘要】 压缩全息将压缩感知理论与全息显示技术结合在一起,利用压缩感知理论,可以由少量的测量数目精确地从2D全息图中恢复3D对象.本文将压缩全息理论从单波长情形拓展到彩色物体的压缩全息,同时研究每层图像在轴向上有较多遮挡的3D对象的3DTV压缩重建,最后通过数值实验验证了本文方法的有效性,并探究复杂物体的填充比例对重建质量的影响,以及不同层之间的遮挡位置和噪声对重建质量的影响.更多还原

【Abstract】 Compressed holography combines the theory of compressed sensing with the holographic display technology.Using the theory of compressed sensing,3 D objects can be accurately restored from the 2 D hologram only by a small number of measurements. In this paper, the theory of compressed sensing is extended from the single-wavelength case to the compressed holography of the color object, and the 3 DTV compressed reconstruction of 3 D objects with more overlap in the axial direction is studied. Finally, the validity of the method is verified by numerical experiments and the effect of the filling ratio of complex objects on the quality of reconstruction as well as the effect of the position of overlap and noise on the reconstruction quality between different layers are explored.更多还原
