Cracks formed in concrete due to frost action (or other expansive reactions) can lead to further damage e.g. because they increase moisture transport. The extent of the consequential damage in concrete is likely influenced by the orientation of the initial cracks. Traditional quantification of the crack orientation is a time consuming manual process. In this paper, a method using automatic image analysis is proposed. The method is based on using image gradients to detect cracks and their orientation. The method produces results that concur with visual observation and manual counting in addition to being substantially quicker.
