水中气泡尺度计算的图像处理方法

Computing Underwater Bubble Radius Using Image Processing

舰船尾流场中气泡幕的存在,使得舰船尾流区域的海水的光特性与周围海水的光特性有很大差异,利用尾流场光学特性的异变,可作为水下航行体跟踪、识别和定位目标的重要手段。尾流中气泡大小、浓度对于研究对光在海水中传输特性有很重要的意义。文中给出了在实验室条件下用图像处理方法计算水中微小气泡尺度的方法,实验结果对于研究舰船尾流场的光学特性有实际意义。

Air bubble screen in ship wakes makes seawater in wakes optical characteristic more different with others, which can be used to track, identify and orientate objects in the seawater. The radius and thickness of air bubbles is very important to light transmission characteristic in wakes. The method of computing tiny bubble radius using image processing is given in the article, and the results have practical meaning to study optical characteristic in ship wakes.
