| Popis: | The free-form surface does not has stable texture and feature points. The existing 3D reconstruction algorithms for the free-form surface extract uncertain quantity of feature points which appear in random location because of image noise and different brightness. A novel 3D reconstruction method through projecting a grid on free-form surface is presented. Gridlines are treated as texture on the free-form surface. On the basis, the feature texture is extracted and feature points are precisely matched, the 3D reconstruction is completed according to recognizing and extracting the grid feature. The method is verified its feasibility and validity after applying it on several models. |
