摘　　要：光场相机利用二维影像同时记录空间中光线的位置和方向信息,能够恢复相机内部的光场,为三维重建提供了新的解决思路.围绕光场相机的三维重建问题,本文综述了光场数据获取手段,梳理和讨论了针对光场相机的标定算法,总结和分析了基于光场影像的三维深度信息恢复方法.在此基础上,介绍了当前主要的公开光场数据和算法.最后,展望了未来的研究方向,以期为后续研究者提供参考.Light field cameras use two-dimensional images to simultaneously record the position and direction information of light in space,which can restore the light field inside the camera and provide a new solution for three-dimensional reconstruction.Focusing on the 3D reconstruction of light field cameras,this paper summarizes the light field acquisition methods,sorts out and discusses the calibration algorithms for light field cameras;then summarizes and analyzes the 3D depth information recovery methods based on light field images.In addition,the primary open-source datasets and algorithms related to light fields are introduced.Finally,the future research directions are elaborated to provide references for subsequent researchers.
