| 摘 要： | 利用OpenGL和VC＋＋平台进行原木断层图像三维重构的研究。首先对断层图像进行轮廓形状插值,然后对轮廓线进行连续性处理,最后使用双三次B样条插值曲面来实现轮廓线的三维重构。实验结果表明,本文提供的方法可以很好的将一组原木腐朽断层图像还原为三维立体图,为原木缺陷检测、立木健康评价等方面提供应用理论基础和科学依据。

| Abstract: | Research on three-dimensional reconstruction of log CT image was conducted based on OpenGL and VC＋＋.Firstly,the contour lines of the CT images were interpolated,and then the continuity was got.Finally,the three-dimensional reconstruction of the outline was conducted by bi-cubic B-spline interpolation surface.Experimental results show that the proposed algorithm can restore a group of CT images into a 3D image.It provides theoretical and scientific basis for wood defect detection and health assessments of standing trees. |
