【摘要】：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。
[Abstract]:Due to the influence of special marine environment, the ocean surface has special irregularity and variability of motion state. It is impossible to describe the irregular and dynamic variability of ocean surface in detail, which leads to the problem of low simulation accuracy. A realistic dynamic ocean surface simulation method based on 3D sonar image algorithm is proposed. First, the number of adjacent points of adjacent ocean surface images is calculated, and all the dynamic ocean shallow surface sonar images are matched and combined. According to the edge coordinate information between the nearest adjacent images, the superimposed parts between the two sonar images are analyzed. Two frames of ocean surface sonar images beyond the overlapping threshold range are registered by the ICP algorithm, and detailed realistic dynamic ocean surface simulation is carried out by using the statistical model and the wave generation method of FFT. The simulation results show that the simulation method of 3D sonar image algorithm for realistic dynamic ocean surface simulation is accurate and effective.
