Application of 3D Laser Scanning Technology in Traditional Building Plane and Elevation Mapping
3D laser scanner has the characteristics of digitalization,high accuracy and intelligence. Aiming at the problems of difficult mapping,long time consuming and low accuracy in traditional building plane and elevation drawing,combined with the new 3D scanning tech-nology,taking a historical building reconstruction project in Wuhan as an example,the convenient and efficient Leica RTC360 LT 3D laser scanner is used to scan the internal and external structures of traditional buildings in all directions,combined with Register360 intelligent mo-saics software,the point cloud data obtained in the field are preprocessed,automatically mosaics,QA/QC inspection and optimization,and LGS data results are obtained. Finally,the horizontal and vertical section of the building is drawn with the point cloud results and the 3D real scene model. The results show that the accuracy and efficiency of building plane and vertical section drawing by RTC3603D scanner and supporting office software are good,which can provide basic data support and technical support for the follow-up implementation of urban planning,build-ing protection and other work.
