摘要
针对单一传感器无法解决海洋环境增强现实系统中跟踪注册的问题,提出融合智能手机AGPS、电子罗盘和加速度传感器测定视线方向的多传感器注册与基于海天线特征标识的视觉跟踪注册的混合注册方法,并通过扩展卡尔曼滤波器实现多传感器有效融合以提高三维注册精度。以真实海洋环境及海洋数值预报为例,提出适应海洋动态环境的增强现实框架,利用Vuforia AR实现了原型系统,并对混合注册方法进行了验证。结果表明,该技术框架及注册方法有较强的可用性和实用性,在海洋动态环境的增强现实中具有广泛应用前景。
In view of single sensor can not provide a complete solution for tracking registration in marine environment augmented reality system,we proposed a mixed registration method,it integrates the registration of multiple sensors including assisted global positioning system( AGPS) of smart phone,electronic compass and acceleration sensor measuring the sight direction with the sea-sky-line feature mark-based vision tracking registration,and achieves effective integration of multi-sensor through extended Kalman filter to improve the precision of 3D registration. Taking real marine environment and marine numerical forecasting as the example,we presented an augmented reality framework adapted to dynamic marine environment and used Vuforia augmented reality( AR) to implement the prototype system,and verified the hybrid registration method as well. Results showed that this technology framework and the registration method have strong availability and practicality,and have extensive application prospect in dynamic marine environment augmented reality.
