Scanning and restoration of cultural relics

Scanning purpose

Scanning cultural relics and sculptures through XTOM surface scanning system for 3D modeling, 3D printing, cultural relics restoration, etc.

Inspection purpose

（1）Selection of measuring surface according to the size of the object (various measuring surface and width can be customized)

（2）Select the camera according to the scanning requirement (2.3 M pixels, 5 M pixels, etc.)

（3）Fully automatic splicing, support marking points splicing, unlabeled feature splicing and turntable splicing, etc.

（4）Powerful data post-processing function, with point cloud denoising, fusion, thinning, triangulation and hole repair, etc.

（5）Multiple data output interfaces: point cloud (ASC,PLY, WRL), triangular mesh (STL), texture mapping (OBJ)

Inspection process

（1）Spray imaging agent on object surface and paste marking points

（2）Camera calibration to obtain internal and external parameters

（3）Move the camera or rotate the object to scan from multiple angles

（4）Data processing, encapsulation, modeling, etc.

Case presentation

（1）Seoul Lake Emperor Hanwu: Scanning the model of Emperor Hanwu, and then magnifying it in equal proportion, which greatly shortens the production cycle and cost.

（2）The statues of Liu Zhidan, Xie Zichang and Xi Zhongxun in the Memorial Hall of Shaanxi-Gansu Bianzhaojin Revolutionary

Base were scanned to obtain 3D models for later production and processing.

（3）Cultural relics restoration: Qinglian Temple in Jincheng, Shanxi Province, Tang and Song Dynasty color sculpture scanning repair, scanning the damaged 18 Arhats to obtain point cloud data, and repair the model through the relevant software, and save the digital model.
