Ranma (Infrared photogrammetry)

3D Model

Ranma (Decorative Transom)
Yanagimoto collection
Length: 251 mm, Width:555 mm, Depth:101 mm

The Ranma carvings feature openwork lions, showing the great attention to detail and ingenuity.

　In cultural property surveys, photographic images captured at various wavelengths are used for analysis.
　This time, we used an infrared camera to create a 3D model. You can clearly see the eyes drawn in black ink, which is difficult to observe with the physical eye. Until now, we have been able to observe infrared data with photographs, but by creating a 3D model, we are now able to observe infrared data in three dimensions.
　By using images obtained from various wavelengths, it is possible to map traces of pigments and ink in a three-dimensional manner.
　For the infrared camera, we used the Mamiya ZD, which cuts out visible light.Created from 101 images.
　Compare the data with the data taken by a normal camera.https://skfb.ly/6ADw6
