摘要
为解决具有相似特征的孔洞由逆向工程软件修补准确度较低的问题,通过对三角网格孔洞修补算法进行研究,在此基础上提出基于相似特征对点云数据孔洞修补的算法,并以惠州荷花亭建筑物为研究对象,利用该算法对孔洞进行修补。实验结果表明,该算法修补效果能够准确还原目标物的原有特征,在很大程度上能够提高孔洞修补效率,其修补效果远远优于传统的三角网格修补。而且,与逆向工程软件GeomagicWrap修补效果相比较,能够更充分的考虑孔洞数据的分布特征及与邻域数据的过渡一致性。
In order to solve the problem that holes with similar characteristics are repaired by reverse engineering software with low accuracy,a triangular mesh hole repair algorithm is researched.Based on this,an algorithm for hole repair of point cloud data based on similar features is proposed.The lotus pavilion building is the research object,and the algorithm is used to repair the holes.Experimental results show that the algorithm’s repair effect can accurately restore the original characteristics of the target,and can greatly improve the efficiency of hole repair,and its repair effect is far superior to the traditional triangular mesh repair.Moreover,compared with the repair effect of the reverse engineering software GeomagicWrap,the distribution characteristics of the hole data and the transition consistency with the neighborhood data can be more fully considered.
