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
結合光度學原理，從實驗研究入手，通過用數字相機實際拍攝的典型曲面（球面）的二維灰度圖像，應用非線性最小二乘優化方法研究確定了現有的lambert 、 phong 、 torrance - sparrow和cook - torrance四種常用局部光照模型的光照參數，利用統計分析原理分析了這四種光照模型在當前實驗條件下對實際圖像灰度數據的擬合精度，並對擬合精度較高的torrance - sparrow光照模型加以完善和改進，發展出一種適合於曲面測量的改進光照模型。 -
The design of yarn is a rather important tache, it can easy get the yarn ' s math model according to its geometrical structure, the paper has bright forward a quick illumination - rendering method that based on hsl / rgb, the advantage of this rendering method is its speediness compared with the traditional rendering method such as phong - rendering method. random diffuse algorithm can add the effect of 3d of the yarn
根據紗線的結構建立相應的數學模型，本文提出一種基於hsl rgb顏色空間轉換的快速光照繪制方法，該方法與傳統的光照模型如phong光照模型相比可以在很短的時間內對紗線進行光照效果的處理，加上隨機擴散演算法，使得繪制出的紗線更具有真實感。
