【摘要】 以野猪为仿生研究对象,借助于非接触式激光扫描仪对野猪头部进行了空间各部位的坐标值三维数据点云获取,通过UG/Imageware软件对点云进行了重构,利用CATIA软件对重构后的点云进行了自由曲面重建,并进行了曲线与曲面的处理与分析。结果表明,重建后的曲面与原始点云间的误差平均值为-1.11664㎜;野猪头部脊线在吻突部位的最大曲率值为0.187㎜-1;曲面高斯曲率的最大和最小值分别为0.008㎜-2和-0.002㎜-2。本文工作为仿生起垄铲的研究提供了必要的仿生数值信息。更多还原

【Abstract】 A wild boar was taken as the bionic research object for the ridger. Three dimensional strongpoints of the head of wild boar had been gotten by non-touch laser scanner and pieced together by means of UG / Imageware. The free surface of the head of the wild boar had been rebuilt by means of CATIA. The characteristic curves of the surface obtained had been treated and analyzed. The result shows that the average error, between the rebuilt surface and the strongpoints, is -1.11664 mm. The max curvature of the ridge on the neb of the head is 0.187 mm -1, the max and min Gauss curvatures on the surface are 0.008 mm -2 and -0.002 mm -2, respectively. These results will be significant as the essential data for biomimetics study on the ridger.更多还原
