【摘要】：提出了一种会聚式集成成像法用于增大其3D观看视角。该成像方法包括会聚式集成成像3D拍摄和会聚式集成成像3D显示两个过程。在3D拍摄过程中,各透镜元的3D拍摄视角不再是中心对称的,而是根据透镜元在微透镜阵列中所在的位置来设置其3D拍摄视角,每个透镜元的拍摄视角分别由上、下、左、右拍摄视角组成。在3D显示过程中,设置的参数与3D拍摄时的参数完全相同,图像元节距大于透镜元节距,使得每个透镜元的观看视角互相会聚,从而增大了集成成像的3D观看视角。模拟实验显示:会聚式集成成像的3D视角是常规成像方式的近3.4倍,且消除了串扰。实验结果验证了理论推导的正确性。
[Abstract]:In this paper, a convergent integrated imaging method is proposed to increase its 3D viewing angle. The imaging method consists of two processes: convergent integrated imaging 3D shooting and converging integrated imaging 3D display. The 3D shooting angle of each lens element is no longer centrosymmetric, but is set according to the position of the lens element in the microlens array, and the shooting angle of each lens element is from the top, the bottom, the left, respectively. In the process of 3D display, the parameters set are exactly the same as those in 3D shooting. The pitch of image elements is larger than the pitch of lens elements, so that the viewing angle of each lens element converges with each other. Thus the 3D viewing angle of integrated imaging is increased. The simulation results show that the 3D view angle of converged integrated imaging is 3.4 times that of the conventional imaging mode and the crosstalk is eliminated. The experimental results verify the correctness of the theoretical derivation.
