Study on Detection of Structures Crack Based on Digital Image Technology

Abstract:

The emergence of cracks of structures is the initial omen of the structural damage. From the initial stage, structural cracks which are undistinguishable by naked eyes exist gradually and then contribute to the member damage, structural deformation and systematic instability as well. This paper made a detection and analysis for cracks of cement flooring by utilizing the digital picture technology, converting a color Image into a gray-scale image. Then ,an appropriate threshold was determined to distinguish between cracks and the background in a gray-scale image. Then, an edge-detection method and morphological techniques of dilation and erosion were used respectively to eliminate noise in the corresponding binary images and obtain crack boundaries.The graphic process program developed can be used to process the gained digital pictures .
