摘　　要：为快速、有效地规划客轮翻扣逃生路径并增强其在模拟训练中的指引作用,研究面向混合现实的逃生路径规划问题。以HoloLens为硬件载体,通过Unity构建虚拟客轮翻扣训练场景,采用Vuforia自然标识和视觉同步定位与地图构建(Visual Simultaneous Localization and Mapping,VSLAM)技术融合虚实场景;通过扩展搜索邻域、增大启发函数权重优化传统A^(*)算法,将改进A^(*)算法引入混合现实场景中实时进行逃生路径规划。仿真结果验证了改进A^(*)算法的有效性和优越性,展现了混合现实路径可视化指引的直观性,可有效辅助训练人员逃生。Application of Mixed reality in planning escape paths on passenger ships is studied in order to enhance the effectiveness of the plan and the drill.Based on the hardware HoloLens,the scene of passenger ship overturn is built with Unity.Vuforia and VSLAM(Visual Simultaneous Localization and Mapping)technologies are used to Blend virtual and real scenes.The A^(*)algorithm,that is improved by expanding searching neighborhood and increasing the weight of the heuristic function is introduced into the mixed reality scene to perform escape path planning.The arrangement is tested,which demonstrates its effectiveness and other advantages.
