Application of Terrestrial Laser Scanner in Bridge Inspection: Review and an Opportunity

37th IABSE Symposium: Engineering for Progress, Nature and People, Madrid, Spain, 3 - 5 September 2014Heavy traffic and aggressive environmental conditions can cause unexpected bridge deterioration. Traditional condition evaluation is expensive. An alternative is Terrestrial laser scanning (TLS) which is a non-contact approach that safe, fast, and applicable to a range of weather conditions. This paper reviews applications of TLS on bridge measurement involving geometric documentation, surface defect determination, and corrosion evaluation, and crack identification. Currently, most post-processing of TLS is manual or within third party software. This paper discusses potential approaches to automatic post-processing.European Research Counci
