| With the improving constantly of speed of the computer, the development of Digital Image Process technology is faster and faster. The application in the tunnel engineering of detection technique of deformation based on Digital Image Process is wider and wider too.The deformation measurement of tunnels plays an important role in guaranteeing the security constructed and run in tunnel. With the quickly development and utilization of tunnels and underground space, it is paid close attention to the thing that how to measure the deformation of tunnels quickly and accurately, improve the measurement efficiency and reduce the cost. The thesis sketches the international current situation about the application of digital image processing techonogy in deformation measurement of tunnels; Advance a new method of measuring the rock convergence by the digital image processing techonogy; Consider the characteristic of picture made in tunnel, the target's attribute, such as size, form, color, etc. are carried on research. And a new method of calculating the target's coordinate is proposed, it suitable for tunnel environment; develop the conversion method from pixel distance to the actually one; A suit of applications (TIPS, TUNNEL IMAGE PROCESSING SYSTEM) including image analysis and data post process with GUI has been developed successfully. The indoor test shows: This system is reliable to measure the distance, reach relevant request of sensitivity and precision. This research results is suitable for relevant personnel's consulting, and could be the foundation as practical research of scene.At the same time, the overall design about the software of TIPS is carried out, module's method and function are introduced in detaile. Some effect result of function is provided, direct against actual conditions, statistical analysis to the test result is carried through. |
