With the development of the ancient building construction market, higher requirements havebeen put forward for the current ancient building component construction industry. Currently, theconstruction of ancient buildings still depends on the construction of craftsmen, and the level ofindustrialization and digitization from processing to on⁃site construction is low. The industrialization anddigital development of the industry must be based on standardization and informatization. And thestandardization and informatization construction in the field of ancient building construction needs to beimproved. Through the organic combination of BIM technology and traditional ancient buildingconstruction technology, this study realizes the automatic estimation technology of ancient buildings withhigh efficiency and high precision and provides a new estimation method and idea for the field of ancientbuilding construction and calculation.
