Experimental Investigation on Image-Based Crack Recognition Characteristics

초록

The crack inspection is important to secure the safety of concrete structure. Therefore image based crack inspection system has been developed to replace present manual inspection. To develop the syst First, simulated crack specimens of various widths were produced and attached to concrete walls, and crack images were taken from different distances. em, edge detection is important factor. In this study compares and analyzes the crack extraction performance of each edge operator to automatically detect cracks occurring in concrete structures. And then, crack edges were extracted from taken images using sobel, prewitt, robert, canny, LoG operator and compare the performance of each edge operator.
