Abstract
This paper proposed a method by using integral imaging for computationally reconstructing three-dimensional (3D) images from different viewing points without introducing additional system complexity. In this method, the process of 3D scene sensing is accomplished by using a microlens array to obtain elemental images. The multi-viewing-points reconstruction process is carried out by computationally simulating optical reconstruction. The prototype displays differently directional views with a horizontal or vertical angle pitch of 3°~1°, when the depth range of object is from 150mm to 450mm. The viewing angle of one image point is about 53°. By optimizing the parameters of imaging system, the angle pitch would satisfy the requirement of practical application. The experimental results proving the effectiveness of the method are given.
