The "Hoang De Chi Bao" golden seal was digitized in 3D for the first time in Vietnam since its repatriation by 3D MASTER Company Limited using the world-famous Creaform blue laser handheld 3D scanning technology.

The "Hoang De Chi Bao" golden seal and its journey home

After many years of wandering, the "Hoang De Chi Bao" golden seal - a national treasure of the Nguyen Dynasty - was officially repatriated from France to Vietnam, kept at the Nam Hong Royal Museum - Bac Ninh. With its immense historical and cultural value, the preservation and storage of the golden seal requires the strictest technical standards.

The first 3D digitization of the "Emperor's Treasure" Golden Seal in Vietnam

3D MASTER Company Limited is the first unit in Vietnam to 3D digitize the "Emperor's Treasure" Golden Seal using Creaform's genuine handheld 3D green laser scanning technology - one of the most advanced solutions in the world today.

Previously, many units were invited by the owners of the antiques to digitize the golden seal. However, these units could not meet the strict standards in preserving the antiques, leading to the digitization process not being able to be carried out.

Strict requirements when 3D digitizing the golden seal

The 3D digitization of the "Emperor's Treasure" Golden Seal is not the same as that of ordinary objects. This is a priceless national treasure, requiring the digitization process to meet the highest standards:

• No direct contact with the artifact to ensure no damage to the surface or material.
• Extremely high accuracy, ensuring that the digitized data truly reflects every detail of the artifact.
• No use of reflective powder or markers like conventional 3D scanning technologies to avoid impact on the surface of the object.

Previous traditional digitization methods often require spraying reflective powder or pasting positioning points on the specimen. This poses a potential risk of damaging the artifact, which is not suitable for historical treasures such as the "Emperor's Treasure" gold seal.

3D MASTER – Pioneer in digitizing national treasures

After many rounds of rigorous assessment and evaluation, along with the trust of experts and owners, 3D MASTER was selected to implement the "Emperor's Treasure" gold seal digitization project.

3D MASTER Company is trusted to deploy because:

• Using HandySCAN BLACK+ Elite Limited handheld blue laser 3D scanning technology – reaform's high-end line with an accuracy of up to 12 micrometers, superior to other solutions on the market.
• No dots, no reflective chemical coating, no contact with objects, ensuring absolute safety for antiques.
• Meeting the highest data security standards with ISO 27001 and TISAX certification, giving customers peace of mind about absolute 3D digital data security, ensuring that digital data is not lost or illegally copied.

Benefits of digitizing the "Emperor's Treasure" golden seal

Digitizing the "Emperor's Treasure" golden seal not only has the meaning of conservation but also opens up many opportunities for research and restoration of cultural heritage.

• Store and preserve in 3D model form, avoiding the risk of damage over time.
• Serve historical and archaeological research with high accuracy.
• Recreate treasures in the form of model versions for display, education and cultural promotion.
