摘要
采用三维激光扫描系统对水黾腹部进行扫描,获取其腹部表面三维点云图;利用Imageware软件对点云图等距截取,提取腹部6个节段共7条截断线数据,并采用最小二乘法进行数据拟合,得到水黾腹部表面轮廓线,实现水黾腹部生物模型向数学模型的转化;基于水黾腹部数学模型,进行腹部曲面重构。分析水黾腹部表面几何特征,研究表明水黾腹部的独特几何外形有助于水黾在复杂环境中减少负重,获得升力和前进动力。
Using 3D laser scanning system,3D point clouds of water strider abdomen are obtained.Utilizing Image ware software,isometric intercepting the 3D point clouds,6 segments and 7 transversals of water strider abdomen are extracted.Taking advantage of least square method for data fitting,water strider abdominal surface contour line is obtained.So the biological model of water strider abdomen is successfully transformed into the mathematical model.On the basis of the mathematical model,water strider abdomen surface reconstruction is carried out.Geometric features of water strider abdomen surface are analyzed.It is indicated that the unique geometrical shape of water strider abdomen contributes to reduce load,get lift and motivation in a complex environment.
