真实感动态海洋表面仿真研究

Simulation and Research of Realistic and Dynamic Sea Surface

由于受到特殊的海洋环境影响,使得海洋表面具有特殊的不规性和运动状态的多变性,无法详细对海洋表面的不规则性和动态多变性进行描述,导致仿真准确度低的问题。提出采用基于三维声纳图像算法的真实感动态海洋表面仿真研究方法。先计算相邻的两帧海洋表面图像邻点迭代的次数,将全部的动态海洋浅表层声纳图像实现匹配组合,根据最近邻图像间的边缘坐标信息,分析两个声纳图像帧之间的叠层部分,融合于ICP算法对超出重叠阈值范围的两帧海洋表面声纳图像进行配准,利用统计模型和FFT的波浪生成方法进行细致化的真实感动态海洋表面仿真。仿真结果表明,三维声纳图像算法的真实感动态海洋表面仿真研究方法仿真精确度高,效果好。

Due to the influence of special marine environment, the sea surface has a special irregularity and dy- namic variety, which are difficult to describe in detail, resulting in the problem of low accuracy of simulation. A sim- ulation research method for realistic and dynamic sea surface was proposed based on 3D sonar vision algorithm. The number of adjacent point＇s iteration of the adjacent two frame sea surface images was calculated firstly. All of the dy- namic sea surface sonar images were matched with each other. Based on the boundary coordinate information between the most adjacent image frames, the overlap part of the two frame sonar images was judged to fuse in ICP algorithm. The two frame sea surface sonar images exceeded the overlapping threshold range were rectified. Using the statistical model and the wave generation method of FFT, a detailed, realistic and dynamic sea surface simulation can be car- ried out. The simulation results show that the research method for realistic and dynamic sea surface simulation based on 3D sonar image algorithm has high accuracy, and the simulation results are good.
