基于B样条的明视觉光谱光效率特性曲线拟合

Curve Fitting Based on Visual Spectrum Radiation Rate Characteristic of B-spline

探索了在MATLAB环境下,基于三次均匀B样条的明视觉光谱光效率特性曲线的拟合方法,解决用一般的曲线拟合方法存在的拟合精度不高或曲线形状畸变的问题。结果表明,采用该方法可以较好地拟合明视觉光谱光效率特性曲线。

Under the MATLAB environment, the paper has explored the curve fitting method in terms of the visual spectrum radiation rate characteristic of the three B - spline uniformity, so as to solve the problems of low fitting accuracy or of curve shape distortion of the ordinary curve fitting method. The results indicate that the above method can be put into good use of fitting out the visual spectrum radiation rate characteristic curve.
