| 摘 要： | 探讨了电容层析成像(ECT)系统中利用二维断层图像进行三维表面重建并由三维图像求取两相流中离散相体积和观察其空间位置的方法。首先对二维断层图像序列进行轮廓抽取和细线化，然后进行轮廓匹配和轮廓插值并进行表面重建。初步的仿真结果表明，使用的三维重建算法简单、重建精度高、成像速率快。

| Abstract: | A method of reconstructing 3-D image from a set of 2-D cross sections for Electrical Capacitance Tomography (ECT) is investigated,and method of discrete phase volume measurement of two phase flow based on 3-D image is introduced too. The contours extracting, thinning and tracking are operated from a set of 2-D images, and the process to find matching points of two adjacent contours, to interpolate contours and to reconstruct a 3-D image. The preliminary experimental results demonstrate the simpleness and effectiveness of the methods. |
