Architectural masterpiece enters the digital age thanks to 3D technology

Built in 1317, Hanbyeongnu Hall embodies the spirit of traditional Korean art. From the XNUMXth to the XNUMXth century, it was a favorite haunt of poets and scholars, drawn to its inspiring atmosphere. This architectural masterpiece has been admired for centuries for its elegant simplicity and refined style.

But like so many other monuments, it has had to face the tests of time and the assaults of nature. In 1972, a violent flood caused its collapse. Three years later, it was reborn, carefully rebuilt to perpetuate its legacy.

A monument that has defied the centuries, captured to the nearest micron

The digitization of the pavilion, initiated by the Korean Heritage Service team, had several objectives: to preserve this architectural gem, to provide new access to this cultural treasure, and to allow Korean heritage enthusiasts to discover every detail from a new perspective. To achieve this, it was imperative to have a fast, reliable solution that guaranteed exceptionally precise results.

After several years of collecting 3D data and photographs of the pavilion, the agency in charge of the project was looking for a technology capable of exceeding its expectations in terms of quality and scale. With this in mind, it called on Artec 3D solutions to carry out this delicate mission.

To scan the Hanbyeongnu Pavilion, experts opted for the long-range Artec Ray II LIDAR, designed for scanning large-scale structures. Capable of capturing objects up to 130 meters away, it offers high precision and rich detail. In this project, its high-resolution cameras were essential for rendering photorealistic colors and breathing new digital life into the monument.

In order to obtain a highly accurate 3D model, the specialists exploited the scanner's capabilities to the maximum. Each scan was carefully positioned to ensure perfect alignment of the data. To capture complex or less visible areas, they moved closer to the monument or took additional shots.

For elevated surfaces, the team maximized coverage by mounting the Artec Ray II on a tripod and scanning from elevated points. Finally, a camera was used to capture details in the hardest-to-reach areas, combining scanning and photogrammetry for a highly accurate final rendering.

Faster scans, in more accurate software

The project was perfectly timed with the release of Artec Studio 19 software, which greatly simplified data processing. “The precise alignment and registration features are particularly useful. This process is much faster and more accurate than other software, while remaining incredibly easy to use. With the new enhancements in Artec Studio 19, we will now rely primarily on this software for our needs,” said Chris Park, Artec 3D Ambassador in Korea.

The processing involved merging meshes, refining complex areas, and optimizing colors for photorealistic rendering. “The scanner processed the data at an impressive speed, which made large-scale file management much easier. Thanks to the integration of Artec Studio, the meshing operations were carried out quickly and efficiently,” said a member of the Korean Heritage Service team.

Highly accurate results to bring history back to life

Through this advanced digitalization, a faithful digital twin of the Hanbyeongnu Pavilion has emerged, capturing every architectural detail and nuance of color with remarkable accuracy. This 3D model opens the door to many applications, from conservation to virtual reality, education, and research. The Korean Heritage Service sees this initiative as a major milestone and sees many opportunities for digital twins of this type.

“With advanced scanning technology, we can safely collect and preserve cultural heritage data. Families, schools, educational institutions and businesses now have access to accurate and well-preserved digital heritage. This model not only allows them to explore it from their desks or 3D print it, but also enriches the tourist experience by making it easier to discover heritage sites,” emphasizes a representative of the agency.

As interest in Korean heritage continues to grow, 3D technology is becoming an essential tool to deepen our understanding of historical sites, raise awareness of their significance, and ensure their transmission to future generations. With its rich history and architectural treasures, Korea is fully embracing this digital transformation to preserve and promote its heritage, playing a key role in regional development.
