For consideration of principle of photometry and experimental research, with 2d gray image of typical surface ( spherical surface ) taken with digital camera, and by use of nonlinear least square optimizing method, the illumination parameters of four local illumination models, that are lambert, phong, torrance - sparrow and cook - torrance model, are determined. and with statistics analytical principle, regression analyses are made to compare the fitting precision of these illumination models under the current experiment condition. comparing torrance - sparrow model with others, an improved illumination model for measurement of surface is developed
