提出了一种荧光目标双向特性的测量和建模方法。首先，构建了一个角度光谱测量系统，用于测量各种荧光物体表面的光谱发光辐射率因子。其次，分析了不同入射光和观察方向下发光辐射因子的角度依赖性。观测到的辐射因子，然后可以描述的朗伯模型具有良好的精度。我们还分析了一个白色垫表面的双向反射辐射因子。荧光目标的双谱双向辐射因子的整体特性可以概括为一个简洁的数学模型。最后，使用在单独的测量系统中估计的唐纳森矩阵来执行荧光对象的图像渲染。实验验证了该方法的可行性。
A method is proposed for measurement and modeling of bidirectional characteristics of fluorescent objects. First, a gonio-spectro measurement system is constructed for measuring the spectral luminescent radiance factor of a variety of fluorescent object surfaces. Second, the angular dependency of the luminescence radiance factor is analyzed in different light incidence and viewing directions. The observed radiance factors can then be described by the Lambertian model with good accuracy. We also analyze the bidirectional reflection radiance factor of a white mat surface. The whole characteristics of bispectral bidirectional radiance factors of a fluorescent object can be summarized as a compact mathematical model. Finally, image rendering of a fluorescent object is performed using the Donaldson matrix estimated in a separate measurement system. The feasibility of the proposed method was examined experimentally.
