摘要: D laser scanning technology is now widely and increasingly used to create as-built 3D CAD or Building Information Models (BIM) of existing facilities new construction. Errors occurred during data processing stages cause a higher registration error, which in return lead inaccuracies the modeling stage. The paper introduces its applications. It also reviews consecutive steps creating BIM using identifies sources error inefficiencies at each focus this study on accuracy scanned point cloud as well time requirements for different processes currently practiced operations.
