Abstract：Focused on area of tunnel leakage disaster，a complete set of image processing algorithms，consisting of denoising，sharpening，image segmention，and improving algorithm，are developed for inspecting leakage disaster. By pre-processing，gray translation，segmentation threshold and pattern correction，finally，area of leakage disaster is got. Then，the calibration relation between pixels and actual shot size is got with outdoor tests. And as a convenient，low-costing，visual and highly efficient detection method，tunnel leakage recognition system is developed.
