摘　　要：为研究船舶机舱中虚拟手技术的应用,根据人体仿生学原理,在船舶机舱虚拟环境系统中进行虚拟手介入操控.针对数据手套多关节的特点,根据关节运动数据的变化,得出手指位置的校正方法,建立能满足人手在虚拟场景中运动映射的虚拟手驱动程序.通过将开源场景图形(OSG)程序嵌入MFC,采用相交矢量的碰撞检测方法和映射投影法,实现三维船舶机舱虚拟场景的调用与操控,形成人在船舶机舱场景中漫游与对虚拟设备对象进行介入操控的交互效果,使虚拟环境中介入式操控更加逼真.In order to study the application of the virtual hand technology in the marine engine room, ac- cording to the body bionics principle, the virtual hand interventional manipulation is carried out in the virtual environment system of the marine engine room. In view of multi-joint feature of the data glove, based on the change of joint movement data, the correction method of finger position is obtained and the virtual hand drive program is established that can achieve the mapping of hand motion in a virtual scene. Through inserting 0SG program to MFC, the call and manipulation for virtual scenes are achieved in the three-dimensional marine engine room by the collision detection method of interseetant vectors and the mapping projection method. The interaction effect that people wander in the marine engine room and manipulate virtual devices makes interventional manipulation in the virtual environment more realistic.
