| 摘 要： | 针对三维纹理映射中存在接缝、颜色差异大等问题,采用基于梯度值之和的选片算法,结合一致性检查、全局颜色校正和局部颜色校正等策略,消除影像的模糊、重影与色差,实现无缝纹理映射,同时避免影像失焦和障碍物的影响,试验结果表明,该方法纹理映射效果较好。

| Abstract: | Aiming at the joint and big difference color in the three-dimensional texture mapping, this paper adopts an image selection algorithm based on gradient value summation.Combined with the consistency check, such as global color correction and local color correction strategy, eliminate the image blur, ghosting and color difference, realize the seamless texture mapping, and avoid the influence of image out-of-focus and obstacles at the same time.The result shows that the method of texture mapping effect is better. |
