Real Scene Pickup Method of Elemental Image Array Based on Convergent Camera Array

Limited available methods for the generation of an elemental image array (EIA) may be the most severe bottleneck for the promotion and application of integral imaging. To obtain rich information of three dimensional (3D) real scene at a relatively low cost, and solve the pseudoscopic problem in real display mode, we propose an EIA generation method based on convergent camera array through establishing the optical mapping model between the proposed method and the classical computer virtual generation method. We expound the basic principle of solving the pseudoscopic problem by changing the relative position of object and center of the convergent camera array in this paper. The experimental results indicate that the generated EIA can be displayed without the pseudoscopic problem in real display mode, relative position relationships of the objects in 3D real scene can also be accurately restored. Both preliminary optical experiments and the optical analysis are conducted to prove the feasibility and validity of the proposed method.
