【摘要】 对12电极方形电容层析成像系统进行了仿真计算,针对几种不同的方形管道内流动形状,比较了采用LBP(线性逆反推)算法、Landweber迭代算法和MLRR(多元线性和正则化算法)等三种算法的成像结果,结果表明Landweber迭代算法可以较好的反映管道内的情况,MLRR算法由于所选的系数a的不同,其成像效果有所不同,该方法产生的图像噪音也大,而LBP算法可以定性的快速反映管道情况。更多还原

【Abstract】 Simulate and calculate the 12 electrodes capacitance tomography sensor.Compare the results using different calculate methods such as LBP,Landweber iterative image reconstruction and MLRR methods.The Landweber iterative method has achieved significant improvement over LBP and can image the status of the pipe well.MLRR has not the same results with different a and the image result has noise.LBP can reflect the status of the pipe fast.更多还原
