Abstract
At PLATEAU, 3D city models are being developed, utilized, and converted into open data, but the parks and green spaces are treated as aerial images without height. Japanese gardens are highly regarded around the world as Japan beauty, so it must be beautiful even in 3D models, but garden stones have complex shapes and surface and each stone is one and only, so realistic 3D modeling has not yet developed and has not been widely used. In this study, we used a handy laser scanner used in reverse engineering to test the creation of a 3D model of garden stones with an accuracy of less than a millimeter. For measurement, a gap of 52 cm around the object is required. Garden stones installed in gardens are often not able to remove measurement obstacles, so the parts that can be measured are limited, but they can be used for 3D modeling of Japanese gardens. In addition, if it is a garden stone as a garden material, it was possible to create a 3D model of the entire circumference of the stone by turning it over from top to bottom. It was suggested that a 3D model of the garden stone could be used as an online catalog for garden stone sales.
