InfraDoctor for Airport ; In April 2019, test trials has begun at Mt.Fuji Shizuoka Airport

InfraDoctor for Airports is jointly developed by four companies; Metropolitan Expressway Co., Ltd., Shutoko Engineering Co., Ltd., Tokyu Corporation and Global Infrastructure Management Co., Ltd. We develop the effective management system in an airport utilizing InfraDoctor developed by Shutoko Group.
Using InfraDoctor the survey of pavement conditions and other general management works are greatly reduced. At present, road surface images (using line sensor cameras) and 3D point cloud data of Mt. Fuji Shizuoka Airport has been generated.
Our aims are to further develop new technologies as well as reducing inspection time.
