AI Summary (NQ-processed)
Osaka Institute of Technology, in collaboration with Shimizu Corporation, Enzan-Kobo, and Shrewd-Sekkei, has developed and commercialized "Perch-RIM," a drone system for unmanned measurement of tunnel faces in mountain tunneling projects. The system works by magnetically attaching a drone to steel supports near the tunnel face and using a LiDAR sensor to acquire high-precision 3D point cloud data. This significantly improves safety by eliminating the need for workers to enter hazardous areas prone to rockfalls, while also contributing to cost reduction through shorter work times. The system's effectiveness has already been verified in field tests at several large-scale tunnel construction sites in Japan.
