3D scanning scheme of ancient cultural relics "Dragon Turtle and Beast"

2021-07-13 A+ A A-

Chinese culture has a long history, there are many cultural relics and historical sites, and the art treasures are extremely rich. Some of these historically valuable cultural relics reappeared in the world after a long period of time, but the protection of cultural relics has always been a problem we face. Major museums have also been committed to better preservation of historical heritage, cultural relics digitization, cultural relics restoration and three-dimensional digital display Let us understand the magical skills of the ancients and the heritage of traditional Chinese culture.

Practical problems

This case
  Hualang customer: a well-known domestic museum
  Scanning object: ancient cultural relic "Dragon Turtle"
  Scanning equipment: HOLON760 handheld laser 3D scanner
  Customer demand: Quickly scan the dragon tortoise 3D data model for digital 3D display of cultural relics

Customer needs analysis

The client is a well-known domestic museum, and quickly scans the cultural relics to display 3D digital products. The customer tried to use traditional methods and searched for professional 3D scanning equipment to scan to obtain full-scale 3D data. However, there were deviations in the scan of the contours of the many grooves on the dragon tortoise beast surface, and the overall scanning effect was very unsatisfactory.

Difficulties in detection

1. The size of dragon tortoise is small, the surface is complex and irregular (there are more curved surfaces, contour grooves), because of the cultural relics, it is impossible to spray the developer and paste the marking points, which greatly increases the difficulty of scanning, and many companies in the same industry are unable to do so. There is no good scanning solution.

2. Customers need to quickly scan to obtain three-dimensional data models and full-color scan data display. The use of traditional scanning solutions is not only difficult, but also time-consuming and laborious and unable to achieve color reproduction, and the scan results cannot meet customer needs.

Holon solutions

After fully understanding customer needs and problems, Hualang engineers recommended HOLON760 handheld laser 3D scanner.

The high precision and high speed characteristics of HOLON760 effectively solve the difficulties of traditional scanning measurement. It can quickly and accurately obtain the three-dimensional scanning data of each part of the scanned workpiece, and it is also suitable for the complex and irregular surface of the dragon tortoise beast (more curved surfaces and contour grooves) and the later color scanning processing. It is worth mentioning that the overall effect has also made customers very satisfied.

★Ultra portable, weighs only 0.87kg;
★The measurement accuracy is up to 0.02mm, and the resolution is up to 0.05mm;
★Almost unlimited 3D scanning, suitable for indoor and outdoor measurement tasks in various complex environments.

Scanning process and results

Use HOLON760 to scan samples-import data into professional 3D inspection software-generate high-precision 3D data models-and finally process 3D color data to obtain the final color scan 3D data.
