基于轮廓线法的汽车类外观专利图像三维重建
3D RECONSTRUCTION OF AUTOMOBILE DESIGN PATENT IMAGES BASED ON CONTOUR ALGORITHM
摘要
Abstract
To carry out 3D reconstruction on exterior design patent images of 3-dimensional products is the basic premise of 3D retrieval of exterior design patents.By combining the characteristics of automobile design patent images,we propose a 3D reconstruction approach for automobile design patent images.The approach uses three-view theory and automobile model’s symmetry to determine the distances between the front view and the rear view at different heights according to the top view information and then further obtains the points coordinates in 3D space.For the connection of the wheel part we make a special processing,and construct the quadrilateral facets by using sub-contour connecting method,thus realise the reconstruction of 3D model.Experimental results show that:1 )compared with traditional methods,the rejection rate of error facets has a 1 9.4% reduction;2)the reconstruction effect figure is more close to the actual object.关键词
