The invention relates to the technical field of image processing, in particular to a civil air defense channel blocking method and system, and the method comprises the steps: obtaining the difference degree between blocks in a gray image according to the matching distance features between the blocks in the gray image and the difference of the gray mean values between the blocks; according to the feature of the distance between the edge pixel point of the suspected crack area of the clustering cluster in the grayscale image and the centroid point of the suspected crack area, the possibility that cracks exist in the blocks of the clustering cluster is obtained; obtaining the crack significance of each initial crack pixel point in the target cluster according to the gray difference between the initial crack pixel points in the target cluster and the non-initial crack pixel points and the gradient magnitude of the initial crack pixel points in the target cluster; and carrying out blocking early warning on the civ
