图像插值在ECT三维数据可视化中的应用

Application of Image Interpolation in ECT Visualization of Three-dimensional Data

在电容层析成像(ECT)三维重建过程中,由于传感器侦测数据的局限,以及成像系统内部和外部的因素影响,使得获取的二维图像比较稀疏,图像质量并不高,而且,获取的二维图像可能会有单一像素点出现,导致不可能被轮廓化,这样就导致有一些流形不能被正确的反映.本文从图像插值的角度,针对ECT二维图像进行像素补充,针对ECT断层序列图像进行断层图像补充.仿真结果表明,该方法很好的改善了三维图像的成像效果.

In the 3 - dimension rebuilding process of Electrical Capacitance Tomography （ECT）, because of the limited data detected by the sensor, and the internal and external influence, the 2 - dimension image pix is scarcity, and the quality is not comparafively high enough. At the same time, the 2 - dimension image perhaps includes single pix, so that the profile can not be traced and some flow can not be reflected correctly. From the perspective of image interpolation, this paper discusses how to complement pix according to the 2 - dimension image, and how to complement images between slices of ECT. The simulation result indicates that the method improves the 3 - dimension image rebuilding effect.
