朗伯发射面 (Lambertian Surface)：在某一方向上的发光强度等于这个面垂直方向上的发光强度乘以方向角的余弦，这样的发光面称为朗伯发射面或朗伯体，有时也叫均匀漫射面或均匀漫射体，还常被称做余弦漫射体。 朗伯发射面的出光度与亮度的关系为M=πL。说明：发光强度，是衡量显示屏亮度的重要指标，单...

Lambertian surface reflection modelis replaced by hybrid reflection Model. 提出了一种基于改进反射模型的明暗恢复物体三维形状的线性化方法,即用混合的反射模型代替通用的朗伯体表面反射模型,再将反射函数与Tsai和Shah的线性化方法结合,对图像进行三维重建。
3) Lambertian surface 朗伯表面 1. Sprayed BaSO 4 diffuser plate is the mostLambertian surfaceactually used in spectral radiance calibration known by now. 通过实验测量硫酸钡漫反射板 2 5 0～ 4 0 0nm的半球反射率和双向反射分布函数表明 ,实测的双向反射分布函数与假定漫反射板为朗伯表面根据测量的半球...
While Spectralon panels are largely assumed to be ideal Lambertian surfaces, their actual polarized reflective responses deviate from the ideal by at least a small amount at illumination and viewing angles off surface normal. The Mueller matrix response of four different panels between 10% and 99% ...
SurfaceColor = Emissive + Ambient + Diffuse + Specular 最终表面 = 放射光 + 环境光 + 漫反射 + 镜面反射 放射光: Emissive = Ke Ke 为材质放射的颜色 环境光: Ambient = Ka * GlobalAmbient Ka 为材质环境光反射系数;GlobalAmbient 为全局环境光的颜色 ...
次表面散射(Sub-Surface Scattering):光线可以穿过子表面,在同一表面的不同方向反射,如皮肤; 表面渗色(Surface bleeding):光线穿过表面,在介质中改变颜色到目标表面。 其他例子还有很多,全局光照会比局部光照效果更佳柔和自然,但考虑到其复杂性,应用到实时渲染中也是有一定难度的。
1) Lambertian reflection of the surface 朗伯假设 1. In the field of thermal infrared remote sensing the computation of the effect is often simplified under two assumptions: one is theLambertian reflection of the surface;another is the isotropic downward thermal radiance of atmosphere. ...
Lambertian surfaces represent an important assumption when constructing thermal radiance transfer equations for remote sensing observations of ground surface temperatures. We identify the properties of ground surfaces in thermal infrared regions as Lambertian surfaces via field experiments. Because Lambertian surf...
