The main target of this study is to develop the Marine Casualty Forecasting System (MCFS) based on the Virtual Reality (VR) modeling techniques.
The aim of MCFS is to broadcast the predicted number of marine casualty and the calculated risk level as like daily weather forecasting.
For this purpose, firstly, the data relating to a total of 724 ship casualties in the west-southern sea area (latitude 33°N~35°N and longitude 124°E~127°E) of Korean peninsula in the years 1990~2000 have been compiled, numerical ship casualty D/B (Data Base) constructed and statistically analyzed.
Secondly, the two kinds of visualization method to give easy comprehension of the predicted results to the peoples who have no knowledge about statistical meaning of the ship casualty are explored. Especially, GUI (Graphical User Interface) based visualization method and VR based immersion techniques are mainly adopted in this procedures.
Thirdly, the multiple regression equations and the casualty prediction models were established and then performed fitting tests for the prediction models.
Lastly, the five casualty forecasting and warning systems are developed and then evaluate their usability. The details of five systems are as followings :
(1) GUI Based Casualty Forecasting System (CFS) ; it can be predict the daily number of ship casualty with WCD-LIP (Weighted Cell Distributed Linear-In-the Parameter) model and, display the predicted results at each partitioned open sea area.
(2) GUI Base Casualty Warning system (CWS) ; it can be calculate the time based risk levels for the total studying sea areas and, display the risk levels using bar-graph type with risk criteria.
(3) GUI Based Casualty Forecasting and Warning System ; it is a dual system combined CFS with CWS to give convenient use.
(4) VR based Casualty Warning Visualization System (CWVS) ; it is to visualize the degree of risk levels in the virtual sea space of east-western area using colored six scales. Using this system a user can know more intuitive risky area than that of the CWS.
(5) VR based Sea Environmental Visualization System (SEVS) ; it is to simulate sea environmental states according to the wave height, wave direction, visibilities, clouds and mountains, etc. Using this system a user can understand realistic sea states as their needs.
