A New Methodology for Bridge Inspections in Linear Infrastructures from Optical Images and HD Videos Obtained by UAV

Many bridges and other structures worldwide present a lack of maintenance or need for rehabilitation. The first step in the rehabilitation process is to perform bridge inspection know bridge′s current state. Routine inspections are usually based only on visual recognition. In this paper, methodology communication routes using images acquired by unmanned aerial vehicle (UAV) flights proposed. This provides access upper parts structure safely without traffic disruptions. Then, standardized systematized novel image acquisition protocol applied data acquisition. Afterwards, studied civil engineers damage identification description. specific structural forms completed information. Recommendations about new more detailed should be included at stage when needed. suggested was tested two railway France. Image these performed an UAV its ability provide expert assessment level. main advantage method that it makes possible accurately identify diverse damages specialised engineer go site. Moreover, videos can watched as many needed with no personal movement. objective work describe development tasks system. According proposal, situ replaced obtained from flight trained operator. To aim, image/videos defined study morphology typology elements inspected bridges. Additionally, proposed every type element. recorded information will allow postanalysis affecting evaluate subsequent recommendations.
