| dc.description.abstract | In this paper we discuss a semiautomatic measuring system that can extract images of cracks in the surface of concrete from multitemporal images. An accuracy assessment and analysis of the relationship between expansion of the concrete and crack width are also included. The proposed scheme is comprised of four major components: (1) imaging geometry modeling for camera calibration; (2) initialization and skeletonization of cracks using the developed graphical user interface; (3) automatic crack tracing and width determination; and (4) multitemporal image processing and analysis. The experimental results indicate that the consistency of crack widths between the automatic extraction method and the manual measurement method could reach | |
