木材CT图像的三维重构

运用CT技术对木材进行无损检测,运用多重分型频谱技术可以对木材CT图像进行有效的边缘检测.针对木材CT图像低对比度、原木缺陷边缘提取困难等问题,采用多重分型频谱技术对处理后的图像进行提取,提取的边缘信息清晰完整、准确度较高,为后续的木材CT图像的三维重建提供有效信息.使用线性插值法对木材CT图像进行三维重建,该方法具有便于理解、实现简单和运算速度快的特点.所运用的线性插值法对木材CT图像三维重建的过程有较好重建效果,具有重建图像直观、清晰的优点,这种重建理论为提高木材利用效率和原木的虚拟切割提供了一种有效的思路.

Three Dimensional Reconstruction of Wood CT Image

Computed tomography technology was used for log nondestructive testing, and multifractal spectrum technology was a- dopted to detect the edge effectively in log CT image in this paper. Aiming at the problems of low contrast and difficuhies in extracting the edge of panel defects, muhifractal spectrum technology was used to extract the edge of panel image clearly and accurately. The method can provide effective information for the three-dimensional reconstruction of log CT image. Linear interpolation method was used to rebuild the three-dimensional CT image for wood, which is easy to understand, simple, and fast operation. The method of al- gorithms in this paper has better three-dlmensional reconstruction effect, and the image is direct and clear. The theory of reconstruction provides an effective idea for reasonable utility of wood and virtue cutting.
