Zusammenfassung: | The invention discloses a carbon paper body paper pore structure characteristic acquisition method, which comprises: 1, carrying out two-dimensional electron microscope image collection on a carbon paper body paper sample to obtain an electron microscope image; step 2, carrying out image noise reduction processing on the electron microscope image to obtain a single-channel grey-scale image of the carbon paper body paper; step 3, carrying out image segmentation processing on the single-channel grey-scale map of the carbon paper body paper, and outputting a binary image of fibers and pores; and 4, carrying out statistical analysis on the pore structure characteristics of the carbon paper body paper by adopting a statistical characteristic function and a fractal control function on the binary image. The method can simply and conveniently obtain the pore characteristic information of the carbon paper body paper, and has the advantages of simple steps, convenience in operation and low cost.
