Comparison Assessment of Pier Dimension Measurement with Different Terrestrial Laser Scanner (TLS) Setup Location

Abstract A bridge is a structure that joins two highways and has four distinct parts: the deck, abutment, pier, joist. For safety reasons, this required routine inspections by qualified inspector. Suggesting new approach uses non-contact testing technologies (NCT) will resolve all difficulties related to inspector’s current conventional method’s increased time, expense, labor intensity. Compared traditional approaches using visual inspection, NCT are prospective instruments for assessing state of bridges since they allow quick simple measurement with little disruption traffic. Terrestrial Laser Scanner (TLS) now taught in surveying courses help surveyors perform their jobs more efficiently. The goal study was make technology use better because it requires less human interaction quality results. TLS contains points cloud consisting x, y, z coordinates; hence can produce 3-dimensional (3D) model output. main objective 3D from point data, followed second objective, which compare pier dimension various distance setup location. To achieve configuration Zig Zag location cover configure three measure accuracy dimension. control actual data done measuring Total Station tape. output Cyclone Register360 compared data. results shown produced accurate measurement. Setup depends on suitability work increase
