利用图象处理技术对船体周围波分布的测量实验与研究

提供了利用图象处理技术在曳航水池中测量船体周围波高分布的测量系统及其理论分析，当镭射光平面从曳航水池中射出，根据画像上的明暗边界对自由表面进行了可视化，结合可视化分析和图象处理技术，本文开发了一种对静水和规则波中船体周围波高分布进行的图象测量系统。在曳航水池中为了在图象中获得足够的明暗对比度，需要使用高性能镭射发光器和高清晰度的摄像机。测量解析结果显示本系统不仅适用一般性船而且适用于高速船，还介绍了一种新的对船体周围波高分布测量的实验结果的分析方法。该方法的数值计算应用了广义的最小二乘法，文中提供的测量系统和分析方法对波浪阻力研究和流场模型构造有一定的实用价值。

Measuring Distribution of Wave Heights Around Ship by Visualization and Image Processing Techniques

Presents the graphic measuring system developed by combining visualization and image processing techniques for distribution of wave heights around a ship in static water and regular waves in a towing tank where a high_performance laser generator and a high_clarity video camera are used to achieve adequate contrast,and the way of analysing the experimental results of wave height distribution around a ship,for which,the generalized least square method is used for numerical calculation,and concludes from actual measurements that this system is suitable for both general ships and high_speed ships.
