摘要
提出一种精确、稳健的主动光场深度成像方法。利用结构光照明为场景提供编码信息,光场成像同时记录光线的方向信息和受深度调制的相位信息,相位编码信息可为构建光场深度线索提供强度不敏感的匹配特征,进而精确计算场景深度。实验结果表明,相比于被动方法,所提的主动方法能够获得更高质量的深度效果,实现精确、稳健的光场深度计算。
Abstract
We propose an active method for light field depth computation with high accuracy and high robustness. Structured illumination is employed to provide encoding information so that both direction information of light rays and depth-modulated phase information are recorded in the light field. The phase information can provide intensity-insensitive matching features for constructing light field depth cues. Thus, scene depth can be computed accurately. Experimental results demonstrate that, compared with the passive method, the proposed active method can obtain higher quality depth maps and achieve light field depth computation with higher accuracy and higher robustness.
