摘　　要：以东北鼢鼠最为粗壮的前爪第三趾为研究对象,通过逆向造型技术,采用三维激光扫描仪获得的爪趾点云,并运用Imageware软件对点云进行降噪处理、剖面截取点云、点云拟合曲线、曲线放样等技术,对东北鼢鼠爪趾进行曲面重构。曲面误差分析结果表明,重构后的曲面与原始点云数据的误差在合理范围内。这表明研究采用2次或者多次扫描获得复杂曲面的方法是可行的。The thickest third toe of fore claw of Myospalax psilurus,was chosen as the research object.The surface point clouds of the third toe were obtained through reverse engineering and the surface of the third toe reconstruction after noise reduction processing,profile intercept point cloud,point cloud fitting curve,and curve lofting.The results of this study can provide technical reference for the bionic design of soil components.The results of surface error analysis show that the error between the reconstructed surface and the original point cloud data is within a reasonable range.This research shows that it is feasible to obtain complex surfaces by two or more scans.
