摘要: 舰船气泡尾流场特征检测是舰船隐身性能研究和尾流自导鱼雷制导效能研究的基础,目前用于水中气泡群特征检测的方法主要是基于高速摄影的图像采集法。针对舰船尾流气泡群图像背景噪声大、气泡重叠度高的特点,提出一种基于改进Hough变换的气泡群特征参数提取算法,实现对大数密度、多重叠水中气泡群图像气泡检测及气泡半径分布计算。用上述方法检测实验室采集到的水中气泡群图像的气泡数及尺寸分布,并与图像实际气泡数进行比对,检验了所提算法准确性,为舰船气泡尾流场特征检测提供了新的思路和手段。

Abstract: Characteristics detection of ship bubble wake field is the basis of research on stealth performance of ship as well as guidance performance of wake-guided torpedo. The existing detection method of bubble characteristics is image acquisition based on high speed photography. A bubble characteristics extraction algorithm based on improved Hough transform is proposed. The proposed extraction algorithm can be used for the detection of bubble and the calculation of bubble radius distribution in the large-density and multi-overlapping bubbles images. The bubbles images were obtained in laboratory conditions, and the proposed algorithm was used to detect the number and size distribution of bubbles in these images. The detected result is highly accurate compared with the actual bubble number in the image. The result shows that the proposed algorithm can be used for the characteristics detection of ship bubble wake field. Key
