description The invention discloses an image reconstruction method and device for capacitive coupling electrical impedance tomography, and the method comprises the steps: taking an unsupervised deep convolutional network as prior information to restrain an image iteration reconstruction process of capacitive coupling electrical impedance tomography, and training a deep neural network with random initialization network parameters, according to the method, the network can learn intrinsic hidden information of the network from a noise label image, a local optimal solution of the noise image is gradually found through operations such as alternate weighted average summation in the training process, a result similar to a real image is generated, and denoising is completed. According to the network prior applied to capacitive coupling electrical impedance tomography, a mode similar to manual prior can be formed to carry out noise constraint on image reconstruction, intelligent parameter adjustment can be carried out according t
