As a collaborative research achievement by SFC laboratories, we have released the 3D point cloud map " SFC Pointcloud 2020 ," which covers the entire campus.
The SFC point cloud map, with an accuracy of 3 cm to 10 cm, was completed by overlaying data scanned by a LIDAR sensor from the ground onto a 3D map created from images taken by a drone from above.

The Hiroya Tanaka Laboratory is further extracting steps and slopes from this point cloud to create a "Barrier-Free 3D Map" that visualizes areas accessible (and inaccessible) by wheelchair.
In addition, new applications have emerged in laboratories across various fields, such as measuring the distances and dimensions of SFC's buildings and tree arrangements, and digitizing the forest to select which trees to preserve when constructing new facilities.
There are also SFC students researching new methods for 3D scanning trees.
In the future, it is expected that this data will be used for a wide range of research, depending on the ideas that emerge.
It is SFC's role to release data necessary for research and education and to pioneer completely new and previously unconceived applications for point clouds.
