摘要:

 阵列相机是一种采集光场的常用方法,可以对多路光场直接采集,但是对于每一路光场都需要一台相机设备进行采集,成本较高、体积庞大。本文提出一种基于压缩传感的光场采集与重建
方法,这种方法使用少量相机组成稀疏相机阵列采集部分光场,利用超冗余字典,实现原始光场的重建。实验结果表明,稀疏相机阵列可以采集光场,并利用压缩传感技术训练合适的超冗余字典恢复出
较高质量的原始光场。

Abstract:

Camera array which can capture multiple views of light filed directly is used as a common light field acquisition equipment, but camera array is difficult to
maintain and high cost as for each view one camera is needed. This paper proposes a method of light field acquisition and reconstruction based on compressive sensing. Much fewer
cameras are used to achieve the functions of full-populated camera array. The sparse camera array captures fewer views and reconstructs the original light field by an over-
complete dictionary. The experiments demonstrated it is feasible to reconstruct the original light field at a high quality level.
