Application of image processing technology on measurement of material surface deformation |

Abstract: | The measure system was designed for the mechanics characteristic of C/C composite material at high temperature through analyzing C/C composite material of the relation of stress and strain. The C/C composite material architecture and the principle of measuring C/C composite material test specimen at high temperature based on the CCD image processing technology are presented. And the incorporated objected image of C/C composite material was obtained at high temperature and the image border was calculated by the use of Sobel operators. Through the change of coordinate, the deformation experiment numerical value of C/C composite material at high temperature was got. The design method of the image processing in the measuring system was analyzed and the curves of the experiment result are shown. |
