摘要
利用数字摄影测量技术对一件馆藏元青花瓷瓶进行数字三维重建。利用物体在影像上的成像轮廓,结合物体的制造工艺,采用类似断面扫描的积分方法,利用在多张影像上精确提取的轮廓位置作为约束,用最小二乘迭代来求解物体上一系列横断面的三维尺寸。选取每幅影像的最佳区域进行纹理重组织,并自动消除影像之间的接边差异。重建结果表明,该方法几何精度高,纹理真实,自动化程度较高。
By using digital photogrammetry method, A Yuan Dynasty blue-and-white porcelain is reconstructed. Based the profile of object in photos, and the manufacturing technology of porcelain, using a method similar as profile scanning, the accurate profile in multi photo as the constraint, the parameters of object are calculated by using the least square iteration. The best texture range in every photo is selected and the merge line is removed for texture mapping. The result of 3D reconstruction shows that the method is of high accuracy, high reality, and high automaticity.
