导助航信息的三维可视化系统研究
Rsearch on 3D visualization system of guided navigation information
摘要
Abstract
The 3D visualization of guided navigation information provides a clear and intuitive scene for the crews, which is convenient for the crews to accurately judge and grasp the spatial location of ship,marine hydrological environ-ment,direction of sailing and other important information.This paper analyzes the architecture of the entire 3D visualiza-tion system and researches on the key technology of the 3D visualization of guided navigation information. The paper achieves coordinate transformation from geographic coordinate system to the world coordinate system by Oblique Merca-tor projection,proposes a method to calculate the position and deflection angle of the beacon to indicate the location of anchorage and ship docked mode,displays dynamically guided navigation information by geometric object visualization. The experimental results show that the system can well solve the ship sailing retention problem caused by low visibility during the ship sails in fog,guiding the ship navigation and positioning.关键词
