Abstract
In this paper, a wild boar head was taken as the bionic research object for the development of new ridgers, a kind of plough. The reverse engineering technology was adopted to obtain the surface geometrical information of the head. Several three-dimensional (3D) point clouds of the head were captured first using a non-touch laser scanner, and an integrated point cloud was generated by aligning these point clouds using UG/Imageware. Then, the digital surface model of the head was rebuilt by means of CATIA. The characteristic curves of the surface model were analyzed. The results show that the average error between the rebuilt surface and the point cloud is −0.431 mm. The max curvature of the ridge on the neb of the head is 0.187 mm−1, and the max and min Gauss curvatures on the surface are 0.008 mm−2 and −0.002 mm−2. These geometrical information are the essential parameters for biomimetics study of the ridger.
