Claim 0:
1. A method for recognizing a geometric regularity image of a honeycomb structure, comprising the steps of image acquisition, image processing, vertex extraction, cell reconstruction, and quality evaluation, the step of image acquisition comprising shooting an image and reading the image by a computer; the step of vertex extraction being to find and record vertexes of cells based on the image processing; and the step of cell reconstruction being to acquire a reconstructed cell image by connecting the extracted vertexes according to a mapping relationship between the cells and the vertexes, wherein
a step of binaryzation is set between the step of image processing and the step of vertex extraction, and is to set a pixel value of a background in the image to be 0 and set a pixel value of a honeycomb skeleton in the image to be 1 to form a binary image, and
the step of quality evaluation is to calculate angular deviation values of all the cells and an average thereof as well as linear deviation values and an average thereof based on the reconstructed cell image, and determine whether the honeycomb structure is qualified or not by comparing with a set tolerance zone.
