Abstract

The development of increasingly sophisticated technology in the field of survey has resulted in more terrestrial laser scanners were being used to generate 3D models such as buildings, slope, landslide and others. This is because laser scanners are capable of making measurements in a short period of time but still provides good accuracy of the millimeter level. However, the laser scan data is static and cannot be applied for other 3D uses. In this project, a building located at Kolej Rahman Putra has been selected to produce 3D CAD model from laser scanned data. FARO Photon 120/20 laser scanner was used to scan G24 building to produce 3D point clouds of the building. This FARO laser scanner is the world fastest 3D phase shift and capable to scan more than 900, 000 points per second. FARO Scene software was used for data filtering and registration. Then, the scanned data was imported into AutoCAD 2011 for processing. 3D point cloud data is then processed into a 3D CAD model of the building. Dimensions of the building were measured using Leica Distometer for quality checking. Furthermore, this laser scanning technique was compared with close range photogrammetry to produce the same 3D building model. A Nikon D3100 DSLR camera with 14 Megapixel resolutions and a Photomodeler Pro 5 software was used for this purpose. Both 3D models were assessed in term of visualization and accuracy to determine the results
