摘要:
针对钕铁硼永磁体产线快速检测与缺陷反馈工艺系统对表面结构完整性及细节特征定量表征的需求,及传统单视角采集存在的覆盖率不足、缺陷细节丢失等问题,提出一种基于多视角转台与双姿态配合的钕铁硼永磁体三维点云构建方法。通过转台参数标定与标定块姿态变换配准,对永磁体在两种固定姿态下的点云进行拼接融合。实验结果表明,多视角双姿态点云重建方法能够实现表面覆盖率超过95% 的三维点云重建,点云拼接精度的均方根误差为0.15 mm,可用于永磁体三维表面缺陷分析。
Abstract:
To address the need for quantitative characterization of surface structural integrity and fine features in the rapid inspection and defect feedback system for neodymium-iron-boron（NdFeB）permanent magnet production lines，and to overcome limitations such as insufficient coverage and loss of defect details caused by traditional single-view acquisition，a 3D point cloud reconstruction method is proposed based on a multi-view turntable and dual-pose coordination. By calibrating turntable parameters and performing pose transformation-based registration using a calibration block，point clouds of the permanent magnet under two fixed poses are aligned and fused. Experimental results demonstrate that the proposed method achieves a surface coverage of over 95% in 3D reconstruction，with a root mean square error of 0.15 mm in point cloud registration accuracy，making it suitable for 3D surface defect analysis of permanent magnets.
