Visual angle enlargement method based on effective reconstruction area

Abstract

The traditional integral imaging system has a small viewing angle, mainly due to the existence of interference pixels in the generated element image. At the same time, in the 3D reconstruction scene, the content that is not in the effective reconstruction area will also cause image crosstalk between adjacent viewpoints, which affects the display angle. In this paper, a viewing angle enlargement method based on an effective reconstruction area is proposed to establish the correspondence between the point pixels in the element image and the micro-lens in the micro-lens array, and the pixel information in the pixel recombination area is derived and updated. The effective reconstruction area is used for constraint, so as to enhance the effective use of the element image information. The experimental results show that the element image with the pixel update has a larger viewing angle and clearer reconstruction content.
