  • 摘要:3D scandata have become increasingly popular for the preparation of survey drawings in wooden architectural heritage. The objective of this study was to identify the pros and cons and characteristics of 3D scandata. Along with survey record sheets and photographs, 3D scandata are raw survey data that are produced directly on-site. These raw survey data are then further processed in an office in order to be used as survey drawings. Among those three items, 3D scandata most notably convey the overall shape, location, and dimension of the heritage, while also providing accurate measurements allowing for more accurate survey drawings. However, 3D scandata are somewhat limited in that they do not provide certain information such as colors, materials, and coupling schemes. 3D scandata are obtained in the field, but are usually processed and screened in an office. Some of the 3D scandata are selected to make survey drawings. Therefore, they can serve as useful complements to other types of raw survey data. Furthermore, 3D scandata are beneficial to the tracing of changes in structures, and can also be used for maintenance management and the development of BIMs. In essence, surveyors are required to perform 3D scanning, as 3D scandata can enhance the accuracy of survey drawings and are utilizable in other valuable ways.
