摘要
针对图像重建问题,介绍了电容层析成像的系统构成及基本原理,多分辨率图像融合方法和融合规则,并对预处理投影Landweber算法和改进的Tikhonov正则算法所仿真的结果进行图像融合。结果表明:融合图像成像精确度明显地提高,去除冗余信息后的图像更接近原型,可应用于现场两相流的实时图像重建。
Regarding image reconstruction, an introduction is being presented to the configuration and fundamentals of electrical capacitance tomography, and the fusion method and rules of multi-resolution image. Image fusion has been made with simulation results from pre-processing projection Landweber algorithm and improved Tikhonov regularization algorithm. Results show that with image fusion technology, high resolution imaging can be obtained, indicating by high similarity of imaging to prototype after removal of redundant information, which therefore can be applied to real-time on-site image reconstruction of two-phase flow.
