【摘要】:由于受到特殊的海洋環(huán)境影響,使得海洋表面具有特殊的不規(guī)性和運(yùn)動狀態(tài)的多變性,無法詳細(xì)對海洋表面的不規(guī)則性和動態(tài)多變性進(jìn)行描述,導(dǎo)致仿真準(zhǔn)確度低的問題。提出采用基于三維聲納圖像算法的真實(shí)感動態(tài)海洋表面仿真研究方法。先計算相鄰的兩幀海洋表面圖像鄰點(diǎn)迭代的次數(shù),將全部的動態(tài)海洋淺表層聲納圖像實(shí)現(xiàn)匹配組合,根據(jù)最近鄰圖像間的邊緣坐標(biāo)信息,分析兩個聲納圖像幀之間的疊層部分,融合于ICP算法對超出重疊閾值范圍的兩幀海洋表面聲納圖像進(jìn)行配準(zhǔn),利用統(tǒng)計模型和FFT的波浪生成方法進(jìn)行細(xì)致化的真實(shí)感動態(tài)海洋表面仿真。仿真結(jié)果表明,三維聲納圖像算法的真實(shí)感動態(tài)海洋表面仿真研究方法仿真精確度高,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.
