| 针对传统集成成像系统视角受限于单元透镜尺寸 及其焦长的问题,提出了一种基于非均匀棱镜 阵列的三维集成成像视角增强方法。以传统集成成像重构显示原理为基础,借助于非均匀棱 镜阵列对重构 光线的偏转作用,设计了显示透镜阵列和非均匀棱镜阵列组合的立体显示模式。依据集成成 像的三维重构 显示原理,利用光线追迹理论,导出了非均匀棱镜阵列的结构参数和集成成像系统视角之间 的关系模型。仿真实验表明,基于非均匀棱镜阵列的集成成像系统视角比传统集成成像系统 有了显著提高。 |

| In conventional integral imaging,the viewing angle is limited by the pitch and focal length of element lens of the lens array.In this regard,a three-dimensional integral imaging di splay system with non-uniform prism array placed in front of the display lens array is proposed to realize a wide vi ewing angle for the three-dimensional reconstructed image.The size and shape of element prism of the non-uniform pri sm array are the same to those of the element lens of display lens array.In our scheme,based on the display principle of conventiona l integral imaging,a three-dimensional integral imaging display model with lens array and non-unifo rm prism array is designed theoretically by using the deflection ability of non-uniform prism array to the reconstruction light.The optical property of non-uniform prism array is analyzed from the point of integral imag ing.A comparison of the viewing angle property between the conventional integral imaging and the propose d method is made.In addition,based on the reconstruction principle of an integral imaging system,the ray tracing t heory is utilized to derive the quantitative relationship model between the structure parameters of the non-uni form prism array and the viewing angle of the integral imaging system.Finally,the simulation results s how that the viewing angle of the proposed method has been significantly improved compared with the conventional i ntegr al imaging system. |
