无深度反转的集成成像一次拍摄方法

One-Step Shooting Method for Integral Imaging Without Depth Inversion

针对传统集成成像显示技术存在深度反转,需要进行二次成像的问题,提出一种无深度反转的集成成像一次拍摄方法。该方法采用离轴平行式集成成像拍摄结构对三维(3D)场景进行拍摄,通过设计合理的拍摄参数,重排图像元,生成无梯形畸变的图像阵列(EIA),直接用于集成成像显示,解决了传统集成成像的深度反转问题,避免了复杂且繁琐的图像校正和二次成像过程,可快速生成具有正确深度信息的EIA。该方法所获取的EIA在集成成像3D显示实验中重建的3D图像具有正确的深度和逼真清晰的立体显示效果,验证了本文方法的正确性。

A pseudoscopic problem often exists in traditional integral imaging display,and is typically solved using two-step shooting process.In this paper,a one-step shooting method for integral imaging without depth inversion is proposed.In this method,the off-axis paralleled shooting scheme is adopted to shoot a three-dimensional(3D)scene and generate an orthoscopic elemental image array(EIA)by reasonably designing the shooting parameters and rearranging the set of elemental images.The generated EIA can be directly used for integral imaging display without depth inversion.The proposed method avoids complex image correction and the tedious two-step shooting process and can quickly generate the EIA with correct depth information.In 3D integral image display experiment,the 3D images reconstructed based on EIA are vivid and clear.The experimental results validate the efficacy of the proposed method.
