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.
