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
3D Visualization Method for Surface Defects of Underwater Structures Based on Acoustic and Optical Combination Measurement
摘要
Abstract
Accurately grasping defect feature information on the surface of underwater structures provides a scientific basis for the health diagnos-is and safety assessment of these structures.This study presents a three-dimensional visualization method for surface defects of underwater struc-tures 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 techno-logy.Then,a sound and light feature data matching method is proposed,comprehensively considering typical target features.Using defect fea-tures in a local single optical texture image as the search target enhances the matching degree of sound and light data,enriching the detail informa-tion in the global concatenated texture image.Finally,a three-dimensional visualization system for surface defects of underwater structures is de-veloped by constructing a texture feature image enhancement algorithm,synchronously utilizing sound and light combination data.The results in-dicated that the combination of sound and light measurement technology improves the efficiency and accuracy of surface defect detection in un-derwater 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.关键词
