Data for: Optimization of five-parameter BRDF model based on Hybrid GA-PSO algorithm

There are 501 rows and 36 columns; each represents a wavelength; 1-501 rows correspond to the wavelength of 400-900 nm; each column corresponds to a different receiving angle. When the incident angle is different, the receiving angle of each column is different.
The definition of incident angle: the angle between incident angle and plane normal.
The definition of receiving angle definition: the angle between receiving angle and plane normal, if receiving angle and incident angle are on the same side of normal, then receiving angle is negative, and receiving angle and incident angle are on both sides of normal.

该数据集包含501行与36列。每行对应一个波长，其中1至501行分别对应400~900 nm的波长范围；每一列对应一个不同的接收角，当入射角度不同时，各列对应的接收角亦各不相同。
入射角的定义：入射光线与平面法线之间的夹角。
接收角的定义：接收光线与平面法线之间的夹角；若接收角与入射光线位于法线的同侧，则接收角为负值；若接收角与入射光线位于法线的两侧，则接收角为正值。
