植物叶片生长并及时改变它们的方向以及它们的叶绿素荧光发射。所有这些动态的植物属性可以半自动监测的三维成像系统，生成植物模型的编码光照明，荧光成像和计算机三维重建的方法。在这里，我们描述了该方法的要点，以及系统硬件。我们表明，该技术可以重建，具有高保真度，叶的大小，叶角和植物高度。当叶子重叠掩盖了它们的真实面积时，这种方法对枯萎的植物无效。当该方法应用于测量水分胁迫下的植物生长时，这种效应自然也会干扰。然而，该方法是非常有效的，在捕捉植物的动态下，轻度胁迫和无应力。3D重建也是非常有效的校正几何因素，扭曲自然定位的植物叶片的叶绿素荧光发射的测量。
Plant leaves grow and change their orientation as well their emission of chlorophyll fluorescence in time. All these dynamic plant properties can be semi-automatically monitored by a 3D imaging system that generates plant models by the method of coded light illumination, fluorescence imaging and computer 3D reconstruction. Here, we describe the essentials of the method, as well as the system hardware. We show that the technique can reconstruct, with a high fidelity, the leaf size, the leaf angle and the plant height. The method fails with wilted plants when leaves overlap obscuring their true area. This effect, naturally, also interferes when the method is applied to measure plant growth under water stress. The method is, however, very potent in capturing the plant dynamics under mild stress and without stress. The 3D reconstruction is also highly effective in correcting geometrical factors that distort measurements of chlorophyll fluorescence emission of naturally positioned plant leaves.
