Key technologies of 3D scene construction for remote assisted driving of intelligent ships

  Objectives   In order to achieve the shore-based remote monitoring and management of navigation in the life cyle of intelligent ship.

  Methods  Through the real-time acquisition and fusion of ship situation information regarding navigation, and the dynamic and static target information of the ship, VR technology is used to reconstruct and present a navigation scene in way of omni-direction and multiple angle of view, a ship collision risk prediction model is established and the three-dimensional dynamic display of the navigation risk relationship between surrounding ships is created.

  Results   The system can accurately display the real scene and state information of the ships during voyage, and provide a three-dimensional and multi-perspective "look-out" function. It not only provides comprehensive navigation information for ship pilots, but also achieves shore-based remote assistance driving support.

  Conclusions   The results of this study can provide technical support and guarantees for the construction of integrated ship-shore intelligent systems.
