Terrain Data Presentation System for Mobile Travel of Remotely Operated Construction Equipment

In the construction industry, remote control of construction machines is highly demanded to improve productivity. A major problem of teleoperation is that the operator cannot accurately understand the surround environment, resulting in the risk of tipping over or collision. For example, three-dimensional (3D) information such as the height of obstacles, the depth of the excavated hole, and the slope angle, cannot be obtained when traveling. In this study, we propose a system to visualize such 3D information of a construction site for operators to avoid hazards during remote-controlled traveling by utilizing 3D terrain data of the site.
