| 摘 要： | 图像重建算法是过程层析成像(Process Tomography,PT)中的关键技术之一.本文提出了一种动态滤波反投影算法(Active Filter Linear Back Projection,AFLBP),并进行了实验仿真.结果表明,采用AFLBP对ECT系统中图像进行重建,可使系统在保持快速成像的同时,较好地解决了敏感场的非均匀分布和固定灰度阈值造成的成像精度问题,大大提高了系统的成像精度.

| Abstract: | The image reconstruction Algorithm is one of the key technology in electrical capacitance tomography(ECT).In this paper,Active Filter Linear Back Projection(AFLBP) method is presented and simulated.Results show that AFLBP method can solve the peoblem of reconstruction accuracy caused by inhomogenous of sensitivity distribution and constant grey level threshold of pixel.With this new method,image can be reconstructed with better accuray at a higher speed. |
