3d laser scanning and 3d printing technologies conserve historic buildings and cultural relics

The Hong Kong antiquities and monuments office combines technology and technology to apply 3d laser scanning and 3d printing technology to the conservation of historical monuments and heritage. The Hong Kong heritage discovery museum will hold a special exhibition on Sept. 21, solstice and Dec. 2 to show the results of the two technologies to the public, the government said on Sept. 19.

In 2016, the amo set up a 3d scanning team to collect accurate 3d measurement data for historical buildings, such as ancestral halls, lighthouses, temples and churches, as well as stone carvings and archaeological relics, using laser pointer scanning technology.

These data can be used to make plans to monitor the condition of historic buildings and to restore cultural relics. They can also be used to make physical print models for reference, research and reference in future renovations.

Since its inception, the 3d scanning team has scanned 24 declared monuments and more than 30 architectural components, sculptures and cultural relics. According to the introduction, 3d laser scanning can accurately collect 3d data in a very short time, which is particularly suitable for ancient buildings and cultural relics, because it is non-contact and can protect the scanned objects, while many structures of ancient monuments are irregular, and the new technology can save manpower and material resources more than traditional measurement.
