[CS2-17] Analysis of 3D reconstruction by photogrammetry measurements for Pavement crack analysis
Keywords:i-construction, 3D model, Crack analysis
The development of Information and Communication Technology (ICT) in the construction field is expected since the announcement of i-construction by the Ministry of Land, Infrastructure, Transport and Tourism (MLIT). The purpose of the trial work was to analyze pavement crack by 3D model reconstruction built from photographic measurements and laser scan.
As a conclusion, the 3D model reconstruction by photogrammetric measurements provided more details for the purpose of pavement crack analysis especially on R56 construction site due to its small area, while the laser scan provided highly accurate point cloud coordinates for the purpose of area and volume calculations.
