摘要:: 为帮助船舶驾驶员快速获取船舶避碰信息以及航行中其他物标信息，利用增强现实抬头显示技术和增强信息投影算法，分析驾驶员、目标船和本船挡风玻璃三者之间的空间关系，建立了从海面会遇船舶到投影设备屏幕坐标，以及与人眼几何投影关系的数学模型，提出了一种基于AR-HUD的辅助瞭望系统架构。通过计算机仿真，建立本船与两条目标船会遇局面，并根据驾驶员观察的方向，投影对应避碰信息。仿真结果验证了AR-HUD技术在船舶值班辅助瞭望中具有较强的适用性。

Abstract:: In order to help duty officers to quickly obtain ship collision avoidance information and other object information during navigation，using augmented reality head-up display technology and enhanced information projection algorithms，and through analyzing the spatial relationship among the officer，the target ship and the wind screen on the bridge of the ship，a mathematical model of the screen coordinates of the encountering ship to the projection equipment and the relationship between the screen coordinates and the geometric projection of the human eye is established.A kind of auxiliary lookout system architecture based on AR-HUD is proposed.Through computer simulation，the situation of the ship encountering two target ships is established，and the corresponding collision avoidance information is projected according to the direction of the officer’s observation.The simulation results prove that the AR-HUD technology can be effectively applied in assisting the duty lookout in ship navigation.
