水下高速运动体试验图像的处理方法研究

Image Processing for High Speed Underwater Objects

针对水下高速运动体的试验检测,要对水下运动图像进行相关处理.由于受到水下照明条件限制,水下图像一般都有比较严重的光照不均匀引起的图像质量不佳.采取同态滤波的方法可以有效地削减亮度的不均匀,同时可以对感兴趣的部分进行增强.此处,由于拍摄方式的影响,造成了图像的运动模糊,采用消模糊理论对其进行处理.实验结果表明,同态滤波增强图像方法和消模糊方法对于水下高速运动试验图像的处理十分有效,符合检测的要求。

Because of the limitation of the underwater illumination condition, the image is seriously affected by light nonuniformity. By using homomorphic filtering, light nonuniformity can be reduced and the object feature can be emphasized. In addition, by the effect of the way of taking image, the image is bluring. A method of eliminating the bluring is proposed. The result of experiment shows, that these methods are effective for underwater high speed objects.
