3D Scan Survey of Mural Paintings on the Porbyeok (Exterior Wall) of Daeungjeon Hall at Mihwangsa Temple in Haenam

JANGSUNG HDS is located in Haenam, Jeollanam-do A project to investigate the condition of cracks and displacement by performing a high-precision 3D Scanning on the mural paintings of the eaves of Daeungjeon Hall at Mihwangsa Templewas performed.

Mihwangsa Temple is a branch temple of Daeheungsa, the head temple of the 22nd parish of the Jogye Order of Korean Buddhism, and the Daeungjeon Hall of Mihwangsa is an important cultural heritage of Korea possessing historical and architectural value.

A large number of bracket paintings remain inside and outside the Daeungjeon Hall, and this project... Record the current state of the mural using non-contact 3D data and investigate the extent of cracks and displacement.3D scanning technology was applied in order to.

Acquiring the fine features of mural paintings as non-contact 3D data

In conducting status surveys of cultural heritage, it is important to acquire information as accurately as possible without damaging the subject.

Especially in the case of targets that require minimizing direct contact, such as old murals Using a 3D Scanning, you can acquire the three-dimensional shape information of a surface without direct contact with the target.You can do it.

JANGSUNG HDS precisely scanned the mural on the exterior wall of Mihwangsa Daeungjeon to capture its actual surface shape 3D Point Cloud dataand based on this, we produced basic data to check the crack and displacement status of the retaining wall.

Crack and displacement investigation using 3D scanning

While standard photographs are effective for recording the color and appearance of cultural heritage surfaces, they have limitations in recording the three-dimensional shapes and displacements of the target surface as quantitative spatial information.

Because 3D scanning records the target surface as data with X, Y, and Z coordinates, it can preserve the actual shape and positional information of the mural in three dimensions.

In this project, the acquired 3D data was utilized to enable the review of the following items:.

• Recording of the current 3D shape of the gun turret mural
• Check crack occurrence location and scope
• Investigation of surface displacement and shape change
• Creation of Point Cloud-based Precision Status Data
• Securing baseline data for comparing future changes
• Establishment of basic data for reviewing cultural heritage preservation and restoration

Reference data for comparing changes in cultural heritage over time

Cracks or deformations in cultural heritage require not only checking the current state once, but also Continuous comparison of how things change over timeis also important.

By building precision 3D Scanning data at a specific point in time, you can rescan the same location in the future and compare it with the past data. This allows it to be used as objective reference data to examine whether cracks or displacements are continuously progressing.

Therefore, cultural heritage 3D scanning is not only for creating simple 3D visual materials, but also Establishment of digital data for recording the current status, monitoring deformation, and preservation management of cultural heritagecan also be used for.

Precision 3D scanning and digital recording of cultural heritage

JANGSUNG HDS applies to cultural heritage requiring precise documentation, such as the mural paintings on the wall of Mihwangsa Temple's Daeungjeon Hall, Applying non-contact 3D scanning technology to build the target's actual shape and spatial information into digital dataDo.

of objects requiring preservation, such as cultural assets, murals, stone cultural heritage, and historical buildings, Baseline data for precise 3D scanning, crack and displacement surveys, point cloud generation, or time-series change comparison.If you need, please contact JANGSUNG HDS.
