| 摘要: |
| [目的]目前已有的在三维点模型上的纹理合成方法,是将点模型进行三角面片化后再进行纹理合成操作,本研究的目的是避免三角面化的过程,得到一种直接在点模型上操作的、快速有效的纹理合成方法。[方法]首先,用KD树为三维点模型上的每一点建立领域,然后为每一点在样图中寻找最匹配的纹理值,最后通过基于点的绘制技术完成纹理合成。[结果]本研究方法能在三维点模型上生成连续光滑的纹理,且保持了原样图的纹理结构。[结论]本研究的纹理合成方法是有效的,并且和传统的三维纹理合成算法相比,本方法费时更少、更灵活可控。 |

| Abstract: |
| [Objective] In this paper, we proposed a fast-speed and effective algorithm to synthesize texture over three-dimensional point set surface without triangulation.[Methods] At first, the neighborhoods for every point on three-dimensional point set surface were built through KD-tree.Then the local neighborhood construction was obtained and the most matching point was found in the input sample image for every point. Finally, texture synthesis was finished through point-based rendering.[Results] The experimental results show that our algorithm can generate continuous and smooth texture on the 3D point-sampled geometry, and maintain the texture structure of the original image.[Conclusion] The technique of texture synthesis is effective.Compared with traditional 3D texture synthesis algorithm, this algorithm is less time-consuming, more flexible and controllable. |
