Reverse engineering of a bobsleigh structure using lidar

초록

Recent extreme weather events and natural disasters are causing rapid aging of the ancient structures with cultural value. It has threatened the safety and management of civil structures. The construction design documents of old structures are not kept for such long time. Even if they are, they seem to be mismatched with the design structures due to corrosive effects. For these reasons, Korea has been facing difficulties in maintenance, reengineering and safety evaluation. The purpose of the study is to derive the drawings of the existing bobsleigh structure and compare with its original CAD drawing designs. The reverse engineering was done by extracting 3D cloud point data from terrestrial LiDAR system. The comparison results shows minimum error on the reverse engineered drawings, which shows LiDAR can be used for effective reverse engineering tool which takes very short period of time. © Research India Publications.
