Abstract One kind of image fusion method of electrical capacitance tomography (ECT) based on the reconstructed images of combined-electrode ECT and hierarchical clustering is proposed. Firstly, the combined 8-electrode and 12-electrode array sensors of ECT are constructed, and the excitation measurement schemes of the two combined sensors are studied; Secondly, the hierarchical clustering method is used to cluster the reconstructed images of the two combined electrodes, so as to eliminate the artifacts in the reconstruction process; Finally, the wavelet fusion is carried out using the two clustered images. Experimental results show that compared with the initial reconstructed images, the average relative error is the smallest with the maximum decrease being 23.4%, while the average correlation coefficient is the largest with the maximum increase being 10.56%
