Abstract

The invention relates to a method and a system for reconstructing a light field by applying depth sampling. The method comprises the following steps: acquiring depth sampling pixel values of a targetimage in different scenes; according to the depth sampling pixel values, obtaining projection pixel values of the same light ray at the same position in different planes; and reconstructing a four-dimensional light field through a projection reconstruction image theorem according to the projection pixel value. By adopting the method or the system provided by the invention, light field reconstruction can be quickly carried out, and the spatial resolution of imaging can be improved.

Description

technical field [0001] The present invention relates to the field of light field reconstruction, in particular to a method and system for light field reconstruction using depth sampling. Background technique [0002] The process of collecting the light field is the process of obtaining the intersection point of the ray and two reference planes, and the position of the reference plane determines the type of the light field collection device. One is to record light by setting a reference plane on the object side, such as a camera array, and the other is to record light by setting a reference plane on the image side, such as a plenoptic camera. The camera array is composed of multiple traditional cameras, and the camera array forms a virtual projection reference plane composed of multiple lens projection centers and a virtual imaging plane composed of multiple CCDs (CMOS). The camera array obtains the light radiation intensity of different viewing angles at the same point of t...
