摘　　要：针对水下爆炸流场多参数测量,发展了基于OpenCV图像处理技术的光学法,对水下爆炸实验中冲击波超压进行测量并与理论和数值结果作对比。发现基于OpenCV图像处理技术的光学法能够较好地实现冲击波阵面的捕获与超压测量并实现冲击波传播过程、爆轰产物发展等流场信息的获取,可为光学法在水下爆炸实验中的应用提供借鉴参考。An optical method based on OpenCV image processing technology is developed to measure the shock wave overpressure in underwater explosion experiment.And the measurement result is compared with theoretical and numerical results.The results show that the optical method based on OpenCV image processing technology can capture the shock wave front and measure the overpressure effectively.Based on the method,the development and evolution process of flow field parameters,such as shock wave and detonation product can be obtained.This provides reference for the application of the optical method in underwater explosion experiment.
