High-tech 3D Scanning Helps Restore 3000-Year-Old Crushed Cultural Relics | PR Newswire

HANGZHOU, China, June 30, 2022 /PRNewswire/ — A treasure trove at the higher-profile Sanxingdui archaeological web page in Sichuan Province, China, has been unveiled to the community with a full of approximately 13,000 numbered relics unearthed, which includes 3,155 comparatively intact relics in the newly identified six sacrificial pits. Scantech’s high-precision 3D laser scanners has been made use of for recording and restoring ancient artifacts unearthed. 

Sanxingdui, an historical web-site situated in Guanghan in Sichuan Province, has been regarded as one of the most significant ancient web pages in the world for its extensive measurement and extended time period, and enriched cultural contents.

From the close of 2020 right up until now, archaeologists have been trying to get to uncover the mystery of this ancient civilization by adopting a model-new archaeological investigation method. By leveraging expertise across unique disciplines and fields, they have verified that the web-site is dated to 3000 yrs back, displaying that the historic Shu civilization is an integral component of Chinese civilization.

On-website 3D Scanning for Relics Excavated

Substantial-tech techniques for archaeology has been adopted to bring the allure of these treasure back again to the community, among the which 3D scanning performs an important function. Scantech is glad to be a joint power representing the world’s good craftsmanship and ingenious layout. 

Repair of an Bronze Sacred Tree

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

There is no definite conclusion about the perform of the tree. Some assume it is connected to a type of tree described in Traditional of Mountains and Seas, a Chinese vintage text, and a compilation of mythic geography and beasts. Ancestors of the historical kingdom of Shu utilized these sacred trees to communicate with heaven and earth and present their reverence and awe for their ancestors and gods. 

Challenge of Replicating Artifacts in Broken State

Not like the comparatively intact and delicate artifacts exhibited in a museum, relics excavated in these sacrificial pits were being damaged and crushed. Proof implies that the objects have been shattered and thrown into pits following remaining utilised for ceremonial rites.

Becoming severely crushed, most of the relics excavated from the sacrificial pit of Sanxingdui have been broken into hundreds of items, making them tough to restore. In addition, 1000’s of several years of oxidation and decay make the fix even more difficult. Without doubt, the conditions of these artifacts posed excellent challenges for excavation and restoration. 

Presented the enormous volume of bronze pieces, it was complicated and time-consuming for scientists to replicate all these broken artifacts with their bare palms, which is a lengthy-standing challenge for archaeology. It took a lot more than 10 years for archaeologists to repair service sacred trees No.1 and No.2. Not long ago, the maintenance of sacred tree No.3 has finished.

Workflow of Reconstruction

In advance of conducting any restoration for the fearful tree No.3, the archaeological researchers determined to assemble these items to see what it seemed like virtually. The selection was to to make certain that there is no damage brought about to the object right before genuine restoration and to accelerate the restore course of action. 

The to start with step was to collect details. Traditionally, authorities use common measurement strategies and photography to record details, which requires a very long time. The knowledge captured are usually not full and minimal for use. 

This time, for the Sacred Tree No.3, archaeologists applied 3D scanning to seize the tree’s information. They applied our handheld laser 3D scanner to capture the info of 69 branches of the tree a person by 1. Thanks to its ultra-high scanning price, Scantech’s metrology 3D laser scanner assisted researchers in correctly getting entire 3D knowledge of relic fragments in a limited amount of time.

A model is then generated in 3D computer software to reconstruct 1:1-sized branches. The 3D product was almost assembled by referring to related relics of Sanxingdui from the identical interval. 

Virtual assembly can assist to replicate the divine tree No.3 to its initial sort digitally with out harmful it in advance of the genuine repair. It simulates the restore approach by almost assembling these items, furnishing accurate data for shedding insights on subsequent reconstruction. The details captured were being also saved and can be archived for even more use. 

Following assembling all the damaged parts of the tree No. 3, archaeologists brought this fragile bronze tree back to existence. The archaeology and restoration of cultural relics at the Sanxingdui Website are however in comprehensive swing. We believe that new systems will enjoy a important job in reviving a lot more cultural treasures.
