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

Abstract

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.

Application of Realistic 3D Model in Building Prefabricated Nanomaterial Structure

“…For demolded embedded parts, it will be affected by the joint action of dead weight and bond force (between the precast member and the die), but the bond force can be considered as uniform distribution, so the position of the embedded parts determined when the absolute bending moment of the precast member is minimum is the same as that determined when only considering the gravity effect. Compared with cast-in-place concrete, prefabricated concrete buildings are divided into two parts, namely, precast component splitting and component deepening design [ 27 , 28 ]. The required structural model is directly imported and obtained by the structural calculation software of WinC, avoiding repeated modeling, while the prefabricated components (prefabricated beams, prefabricated columns, and prefabricated panels) are split and designed.…”

4D Epanechnikov Mixture Regression in LF Image Compression

“…Before modeling, the key-EIA was extracted from the original elementary image array (EIA) [44] according to the interval, which is the interval between two extracted EIs. For example, in Fig.…”
