Measuring States of Plant Photosynthesis by Structured Light Projection

我们研究了一系列分离反射分量的计算机视觉技术在提高叶绿素荧光测量精度方面的应用。其中一个主要贡献是我们证实了将结构光投射到植物并分离直接和间接(或全局)分量的方法能够真正提取入射光在植物叶片上的亚表面散射，从而改进了叶绿素荧光的测量。我们还提出了一种基于双色反射模型的镜面反射和漫反射分量分离的新方法。

We have studied the application of a range of computer vision techniques of separating reflection components to improving measuring accuracy of chlorophyll fluorescence. One of the main contributions is that we have confirmed that the method of projecting structured light to plants and separating the direct and indirect (or global) components can really extract sub-surface scattering of incident light onto leaves of plants, resulting in the improvement of measuring chlorophyll fluorescence. We have also developed a new method of separating specular and diffuse reflection components based on the dichromatic reflection model.
