摘要 光场成像方法是智能图像处理中迅速发展的前沿领域,涉及的主要内容是:光学景深的扩展和不聚焦摄影的自适应多重焦平面成像问题的研究。其中包括对光场成像基本原理和硬件结构的介绍,也包括全光函数参数化方法的应用问题的讨论;这是因为,新兴起的计算摄影学、3D可视化、虚拟环境等领域的目的是:全面实现全光函数对外部客观世界的描述;而光场成像及光场相机则是这个目标的一个局部的实现,其中涉及的问题有光信息的采集,光学傅里叶变换,不聚焦摄像的处理和光学景深的扩展方法等。这些研究内容是光场成像和计算摄影学领域中的基础性的重要课题,也是与图像渲染以及3D显示密切相关图像信息中一种全新的处理方法,具有重要的应用价值。在此针对上述各难点问题和关键结构,给出了全面、深入、透彻的分析论述,提出进一步研究的主要内容。该文对当前迅速发展的全光信息处理中关键技术与方法的综述与展望,对相关领域的读者具有一定的参考价值。 The light field imaging method is the advanced field in intelligent image processing. It involves the following research contents:scene depth extension and adaptive multi-focal planes imaging of unfocused photography. In this paper,the basic principles and structure of light-field imaging are introduced,and the application of plenoptic functions′ parameterization method is discussed. The difficult issues and critical structures are comprehensively and deeply analyzed and discussed in this paper. The further research contents are proposed. The key technologies and methods in all-optical information processing in rapid development are summarized and expected,which has important reference value for readers in relevant fields.
