HANGZHOU, China, June 30, 2022 /PRNewswire/ — A treasure trove at the high-profile Sanxingdui archaeological web page in Sichuan Province, China, has been unveiled to the general public with a overall of virtually 13,000 numbered relics unearthed, such as 3,155 somewhat intact relics in the freshly identified 6 sacrificial pits. Scantech’s superior-precision 3D laser scanners has been utilized for recording and restoring historical artifacts unearthed. 

Sanxingdui, an historic web page situated in Guanghan in Sichuan Province, has been identified as one particular of the most critical historic web sites in the planet for its broad sizing and extended time period, and enriched cultural contents.

From the end of 2020 until finally now, archaeologists have been in search of to uncover the secret of this ancient civilization by adopting a model-new archaeological exploration mode. By leveraging skills throughout distinct disciplines and fields, they have confirmed that the web-site is dated to 3000 many years ago, exhibiting that the ancient Shu civilization is an integral component of Chinese civilization.

Superior-tech approaches for archaeology has been adopted to provide the attraction of these treasure again to the general public, amongst which 3D scanning plays an important part. Scantech is glad to be a joint force symbolizing the world’s fine craftsmanship and ingenious structure. 

Maintenance of an Bronze Sacred Tree

The object to be fixed is the bronze sacred tree No.3, just one of eight wonderful trees unearthed from sacrificial pit No.2 of Sanxingdui in 1986.

There is no definite summary about the functionality of the tree. Some consider it is relevant to a variety of tree described in Typical of Mountains and Seas, a Chinese vintage text, and a compilation of mythic geography and beasts. Ancestors of the historic kingdom of Shu employed these sacred trees to connect with heaven and earth and clearly show their reverence and awe for their ancestors and gods. 

Challenge of Replicating Artifacts in Damaged State

In contrast to the relatively intact and delicate artifacts shown in a museum, relics excavated in these sacrificial pits were being broken and crushed. Proof implies that the objects have been shattered and thrown into pits soon after remaining applied for ceremonial rites.

Currently being seriously crushed, most of the relics excavated from the sacrificial pit of Sanxingdui were being damaged into hundreds of parts, producing them demanding to restore. In addition, 1000’s of yrs of oxidation and decay make the mend even more challenging. Certainly, the problems of these artifacts posed great problems for excavation and restoration. 

Provided the monumental volume of bronze items, it was difficult and time-consuming for researchers to replicate all these damaged artifacts with their bare hands, which is a extended-standing trouble for archaeology. It took additional than 10 a long time for archaeologists to repair service sacred trees No.1 and No.2. Just lately, the restore of sacred tree No.3 has ended.

Workflow of Reconstruction

Right before conducting any restoration for the fearful tree No.3, the archaeological scientists made a decision to assemble these pieces to see what it appeared like nearly. The decision was to to make certain that there is no harm caused to the item ahead of genuine restoration and to speed up the repair service approach. 

The 1st stage was to collect data. Traditionally, specialists use regular measurement strategies and photography to document data, which can take a prolonged time. The details captured are generally not total and confined for use. 

This time, for the Sacred Tree No.3, archaeologists used 3D scanning to capture the tree’s data. They applied our handheld laser 3D scanner to capture the knowledge of 69 branches of the tree a single by a single. Many thanks to its extremely-large scanning level, Scantech’s metrology 3D laser scanner assisted researchers in properly obtaining total 3D knowledge of relic fragments in a shorter total of time.

A model is then generated in 3D software program to reconstruct 1:1-sized branches. The 3D design was virtually assembled by referring to very similar relics of Sanxingdui from the same period of time. 

Digital assembly can aid to replicate the divine tree No.3 to its first kind digitally with out harming it before the true fix. It simulates the repair service course of action by virtually assembling these pieces, giving exact info for shedding insights on subsequent reconstruction. The data captured were being also saved and can be archived for further use. 

Immediately after assembling all the broken items of the tree No. 3, archaeologists introduced this delicate bronze tree back to life. The archaeology and restoration of cultural relics at the Sanxingdui Web-site are still in total swing. We feel new technologies will engage in a critical purpose in reviving a lot more cultural treasures.
