针对传统船舶制造检测方法难以满足船体分段复杂曲面高精度检测需求的问题,本文以激光雷达与结构光融合采集的点云为数据源,提出基于曲面曲率的自适应重采样算法,优化点云特征提取流程,并以某船体分段为对象开展对比实验,将本文算法与传统点云处理技术开展对比实验,结果表明,本文方法配准均方根误差小于0.05 mm,偏差检测精度达0.03 mm以内,关键点位一致性系数大于0.95,配准精度、处理效率及超差识别准确率较传统方法均有显著提升,可有效满足船体分段高精度、高效率检测需求。
To address the problem that traditional inspection methods in ship manufacturing cannot meet the high-precision inspection requirements for complex curved surfaces of hull segments, point clouds acquired by the fusion of LiDAR and structured light scanning are used as the data source in this study. An adaptive resampling algorithm based on surface curvature is proposed, and the point cloud feature extraction process is optimized. Comparative experiments are conducted on a real hull segment, in which the proposed algorithm is compared with conventional point cloud processing techniques. The results demonstrate that the registration root-mean-square error of the proposed method is better than 0.05 mm, the deviation detection accuracy is within 0.03 mm, and the consistency coefficient of key points is higher than 0.95. The registration accuracy, processing efficiency, and out-of-tolerance recognition accuracy are all significantly improved compared with the traditional method, which can effectively satisfy the high-precision and high-efficiency inspection requirements of hull segments.
