基于增强现实技术的翻译系统建模技术研究

基于增强现实技术的翻译系统,通过跟踪用户头部位置和姿态的变化将飞机座舱的辅助信息实时显示在头盔显示器上,以软件的形式实现了进口飞机座舱设备的汉化。系统建模包括对系统整体架构的描述和各分系统的数学解决方案:座舱分系统采用将各仪表部件抽象为空间平面的方法来建模,文章介绍了在座舱和跟踪器两种坐标系下的平面方程建立方法;为统一参考坐标系,文章采用最小二乘法对坐标变换矩阵进行参数估计。

Modeling Technology for the Translate System Based on the Technology of Augmented Reality

Tracking the position and pose of user's head,the translate system based on the technology of augmented reality displays assistant information on the HMD in real time,thus,the cockpit components of foreign fighter are translated into Chinese.The system modeling involves the depiction of main framework and the mathematical solutions of subsystems.Cockpit components can be regarded as spatial planes in the abstract,this paper presents two method to establish planar equation in cockpit coordinate system and tracker coordinate system.Using the least square method to estimate the transition matrices,the coordinate systems of subsystems can be unified in the same reference.
