基于前向光线追迹技术的单光场相机空间分辨率研究
Research on spatial resolution of a single light field camera based on forward ray tracing technique
摘要
Abstract
In the process of 3D scene reconstruction,the spatial resolution of the light field camera(LFC)af-fects the recoverable spatial details as well as the depth resolution,thereby influencing the accuracy of the 3D reconstruction.Therefore,calculating and analyzing the spatial resolution of the LFC is crucial for identify-ing the high and low resolution regions.In this paper,a calculation method for the spatial resolution of an LFC is explored based on the forward ray-tracing technique,which has the advantage of high accuracy.The spatial resolutions of LFC 1.0 and LFC 2.0 under different microlens array configurations are quantitatively calculated and compared.In addition,the effects of the inverse magnification(Ml)of the main lens on the depth resolution of the LFC are investigated.The results show that the LFC exhibits higher depth resolution in regions away from the intersection of the object plane and the optical axis.The depth resolution of LFC 2.0 near the region of(0,0,0)is better than that of LFC 1.0.For a microlens array arranged in a square pat-tern,the lateral resolution of LFC 2.0 shows a slight improvement over that of LFC 1.0.The depth resolution of the LFC 1.0 gradually decreases as Ml increases.关键词
