摘　　要：准确掌握水下构筑物表面的缺陷特征信息,能够为构筑物的健康诊断与安全评估提供科学依据。针对目前水下狭小空间环境中,测试设备尺寸受限、与声光数据同步利用和融合难的技术瓶颈,提出基于声光组合测量的水下构筑物表面缺陷3维可视化方法。首先,在利用声光组合测量技术捕获有效数据的基础上,构建能够反映缺陷目标典型特征参数的定量表征方法;随后,提出综合考虑典型目标特征的声光特征数据匹配方法,以局部单幅光学纹理图像中的缺陷特征为搜索目标,提高声光数据的匹配程度,丰富全局拼接纹理图像中的细节信息;最后,通过构建纹理特征图像增强算法,形成同步利用声光组合数据的水下构筑物表面缺陷3维可视化技术体系,并结合实例分析,验证本文方法的正确性与优越性。结果表明,声光组合测量技术能够提高水下构筑物表面缺陷检测的效率和精度,同步利用声波扫描数据和光学纹理信息突显水下构筑物表面缺陷的3维可视化特征,为水下构筑物表面缺陷的3维可视化及定量描述提供一种新的技术方法。Accurately grasping defect feature information on the surface of underwater structures provides a scientific basis for the health diagnosis and safety assessment of these structures.This study presents a three-dimensional visualization method for surface defects of underwater structures based on acousto-optic combination measurement,addressing the technical bottleneck of limited testing equipment size and the challenges of synchronized utilization and fusion of acousto-optic data in narrow underwater spaces.First,a quantitative characterization method that reflects typical feature parameters of defect targets is developed by capturing effective data using a combination of sound and light measurement technology.Then,a sound and light feature data matching method is proposed,comprehensively considering typical target features.Using defect features in a local single optical texture image as the search target enhances the matching degree of sound and light data,enriching the detail information in the global concatenated texture image.Finally,a three-dimensional visualization system for surface defects of underwater structures is developed by constructing a texture feature image enhancement algorithm,synchronously utilizing sound and light combination data.The results indicated that the combination of sound and light measurement technology improves the efficiency and accuracy of surface defect detection in underwater structures.The synchronous use of acoustic scanning data and optical texture information highlights the three-dimensional visualization features of surface defects in underwater structures.This study provides a novel technical method for the three-dimensional visualization and quantitative description of surface defects in underwater structures.
