HangzhouChinaAnd the July 1, 2022 /PRNewswire/ – Treasure mine at Sanxingdui Archaeological Site in . County Sichuan, in China, has been revealed to the public with the excavation of nearly 13,000 artifacts, now numbered, including 3,155 relatively intact artifacts in six newly discovered sacrificial tombs. Scantech’s high-resolution 3D laser scanners were used to record and retrieve the artifacts discovered.
Restoration of the sacred bronze tree
The thing to fix is the Bronze Sacred Tree No. 3, which is one of eight magnificent trees that were excavated in 1986 from the Sacrificial Pit No. 2 in Sanxingdui.
Currently, no final decision has been made on the function of the tree. Some believe that the ancestors of the Ancient Kingdom of Shu used these sacred trees to communicate with heaven and earth and to show their reverence and awe toward their ancestors and gods.
Difficulty repeating broken artifacts
In contrast to the relatively intact and delicate objects displayed in the museum, the antiquities excavated in these offering pits were broken and crushed. The data seems to indicate that the objects were split up and thrown into pits after being used in ceremonial rituals.
Rebuild workflow
Before doing any restoration of the n3 sacred tree, archaeological researchers decided to assemble these pieces to see what they looked like virtually. It was necessary to ensure that there was no damage to the object before the actual restoration and to speed up the repair process.
The first step was data collection. Experts usually use traditional measurement and imaging methods to record data, which is very time consuming. The data entered is generally not complete and its use is limited.
This time, for Sacred Tree #3, the archaeologists used 3D scanning to capture the tree data. use Portable 3D laser scannerTo capture data from 69 tree branches, one by one. With an extremely high scanning rate, Scantech’s 3D laser scanner has helped researchers obtain comprehensive 3D data of trace fragments accurately and in a short time.
Then a model is created in the 3D software to reconstruct branches at a scale of 1:1.
Archeology and restoration of cultural relics at the Sanxingdui site is still in full swing. We are convinced that new technologies will play an essential role in reviving other cultural treasures.
