水面波的图像序列分析

Image Sequence Analysis of Surface Waves

为了分析波浪的传播方向,使图像中的波浪方向数据可视化是一个可行的方法,本文提出了一种基于开源计算机视觉库使图像中的波浪方向数据可视化方案。通过对水面波图像进行波纹线区域拟合,对这些拟合直线的斜率与角度进行统计分析,获取波浪的传播方向信息。实验的结果表明,输出的角度统计数据与目测角度大致相同,说明本方法可使图像中的波浪方向数据可视化。

In order to analyze the propagation direction of waves and visualize the wave direction data in images,this paper proposes a solution based on an open source computer vision library to visualize the wave direction data in images.By fitting the wavy line area of water surface wave images,statistical analysis is conducted on the slopes and angles of these fitted lines to obtain information on the propagation direction of waves.The experimental results show that the output angle statistical data is roughly the same as the visual angle,indicating that this method can visualize the wave direction data in the image.
