多孔介质X-CT图像的三维重建

Three Dimensional Reconstruction of Porous Media X-CT Image

摘要: ImageJ这款开放源代码的图像处理软件在多孔介质重建方面介绍很少。通过使用ImageJ软件对一组海绵的X-CT切片进行处理，着重介绍了ImageJ在X-CT图像三维重建中的应用。本文给出了进行三维图像重建主要的操作方法和几种多孔介质重建的图，为更好地使用ImageJ对多孔介质X-CT图像三维重建，给出了进行三维图像重建主要的操作方法和重建结果。对于重建的三维多孔介质模型，利用数值模拟的方法为进一步研究微观流动及传热机理奠定了良好的基础。

Abstract: ImageJ, an open source code image processing software, is rarely introduced in porous media re-construction. Through the use of ImageJ software, a group of sponge X-CT slices was processed. The application of ImageJ in the X-CT image 3D reconstruction is introduced. In order to better use the ImageJ to three-dimensionally reconstruct the porous media X-ray CT image, this paper gives the main methods of operation and the results of the three-dimensional image reconstruction. For establishing the three-dimensional reconstruction of the porous media model, this paper used the method of the numerical simulation which lays a good foundation for the further research on the micro flow and the heat transfer mechanism.
