摘要:基于三维集成成像理论以及相机阵列和显示透镜阵列之间的对应关系,利用几何成像理论和光线追踪方法对不匹配全光学集成成像记录系统进行了理论分析,得到了主要记录参数(记录距离和相机间隔)和集成成像显示特性之间的关系。提出了一种非匹配系统中相机阵列记录系统参数的设计方法,并设计了相机阵列记录系统。计算得到了系统的关键参数为记录距离49.6cm,相机间隔25mm。对提出的方法进行了实验验证,结果表明,提出的相机阵列光学记录系统能够完整记录场景的三维信息,三维显示特性基本达到了设计指标,相机阵列的主要记录参数与集成成像三维显示特性的关系符合理论分析,验证了提出方法及系统设计的可行性。提出的系统可为不匹配全光学集成成像系统显示提供大场景、高分辨率微图像阵列。

Abstract: On the basis of the principle of integral imaging and the relation between camera array and display lens array, a pick-up system using a camera array for three-dimensional integral imaging was analyzed according to the geometric imaging theory and the ray tracing method, and the dependence of main recording parameters on display characteristics of integral imaging was obtained. A parameter design method for elemental images was proposed according to the display specifications and a pick-up system was designed by the proposed method in a pick-up distance of 49. 6 cm and a camera space of 25 mm. The experimental results demonstrate that the pick-up system using the camera array can record the 3D information for a scene completely and the 3D display characteristics reach to the design re-quirements, Furthermore, the relationship between the pick-up parameters of the camera array and the display characters coincides with theoretical analysis, which verifies the display performance of de-signed system and the feasibility of the proposed method as well. The system can generate elemental
