通过DLT变换建立三维几何模型上的点与相应文物相片上各彩色像素之间的关系。首先，根据点的扫描坐标，计算该点在真彩色像片上的位置；其次，内插出红、绿、蓝三原色；最后，将三维几何模型与真彩色纹理进行最佳融合。建立文物真彩色真实感觉的数字模型，为数字文物和文物保护提供了理论和技术参考。

Firstly, the relationship between points in the 3D geometric model and pixels in the corresponding historical relic color pho-tos is built by Direct liner Transformation(DLT) transformation, then basing on the scanning coordinates of points, the position of points in the true color photos are calculated and three primary colors which are respectively red, glue and blue is interpolated.At last, it makes greatly merge the 3D geometric model with true color veins, and it creates the digital model with true color.This pro-vides the theory and technical reference for digital relic and protection of cultural relics.
