摘要:

针对水下目标检测中实测样本获取困难、传统数据增强方法难以有效表征侧扫声呐目标散射特性的问题,本文提出了一种基于侧扫声呐成像机理的沉船目标样本生成方法。基于声能方程与射线传播模型,构建了顾及回波散射强度特征的沉船目标声学成像模型;然后,考虑海底地形地貌对声学成像的影响,基于风格迁移方法对生成图像进行增强,以提高目标图像的真实性与环境一致性;最后,结合环境噪声模型,对目标图像进行噪声扰动与环境特征增强,生成多场景沉船目标样本数据。试验结果表明,仅利用生成样本训练的检测模型取得了0.88 mAP(0.5)的检测精度,验证了本文方法在少样本水下目标检测任务中的有效性,能够为复杂海洋环境下侧扫声呐目标检测模型的训练提供数据支撑。

Abstract:

To address the difficulty of acquiring real side-scan sonar (SSS) target samples and the limited capability of conventional augmentation methods in representing acoustic scattering characteristics, this study proposes a target sample generation framework based on the SSS imaging mechanism. An underwater target imaging model integrating echo intensity and acoustic ray propagation is first constructed according to the SSS imaging principle and acoustic energy propagation model. Subsequently, considering the influence of seabed topography and geomorphology on acoustic imaging, an improved style transfer strategy is introduced to enhance the generated images and improve their realism and environmental consistency. In addition, an environmental noise model is incorporated to perform noise perturbation and environmental feature enhancement, thereby generating multi-scene shipwreck target samples. Experimental results demonstrate that the detection model trained solely on the generated samples achieves a detection accuracy of 0.88 mAP (0.5), verifying the effectiveness of the proposed sample generation method for few-shot underwater target detection tasks. The proposed method can provide data support for training side-scan sonar target detection models in complex marine environments.
