Research And Implementation Of Digital Image Processing In Tunnel Face Image

On the ground of tunnel development, this paper aims at the research of graph and image processing and its application in analyzing tunnel face images. The application research is very rare around the world, especially in our country. Now the research of tunnel face image processing analogy is still elementary.At first, this paper simply reviews the research background and the history of the face image processing technology study at home and abroad. Then the paper introduces the major research matters, mentions the main problems to be studied, and also promotes the technology ways as possible solutions.This paper studies how to acquire all terrene edge information and investigates the means of linking the same terrene out of various images by pattern recognition, thus provides the data of a 3-demension building for tunnel structure, so as to build a 3-demension model that helps to observe and forecast the tunnel 3-demension structure and finally offers the necessary referenced information on tunnel construction. Compared with traditional analogy methods, the image processing technology is more efficiency, which can largely save the time of tunnel face image analysis. Meanwhile, it reduces the cost. Since its' applications are very extensive, it is necessary to study the applications of computer graphics, digital image processing and pattern recognition technology in tunnel face image.This paper concerns the tunnel face image processing system. Digital image processing technology is the most important part of the system, which mainly includes image fore processing, image segmentation, character acquisition, pattern recognition and so on. The paper introduces the possible arithmetic used in different parts, and...
