The diagnosis of reinforced concrete slabs requires the consideration of four key pieces of information: the presence of cracks, width, length and direction. It is therefore essential that these details are accurately recorded during the inspection process, although it is also important to note that this can be a time-consuming task. In the case of railway overpasses, where inspection work is limited to night-time, the time available for inspection is approximately 30% of that available for general bridge inspections. This highlights the need for the introduction of inspection methods that allow for the accurate recording of more information.This report thus presents a methodology for conducting bridge inspections using digital images, which can be employed in the periodic inspection of railway overpasses where inspection work time and light sources are limited. It also elucidates the impact of differences in equipment specifications and shooting conditions for acquiring digital images from this approach, as well as the impact of these differences on diagnostic imaging services.
