In order to obtain the solid model of automobile end cover with multideep hole feature, the method of model reconstruction was studied. By using Geomagic Wrap to simplify the point cloud data and remove noise,the GA-BP algorithm was used to repair the holes of the cross surface point cloud. By using the forward and reverse design functions of Geomagic Design X, the contour of the deep hole features was intercepted; based on the automatic feature recognition of the point cloud, parametric correction was carried out, and the forward design command was used to complete the reconstruction of the solid model. The deviation between the solid model and the original point cloud data was analyzed by using the Geomagic Control X software. It is verifies that using the modeling idea,the solid model of the automobile end cover can be obtained that meets the accuracy requirements.It provides reference for the part model reconstruction with similar situations.
