| 摘 要： | 点云的孔洞修补是点云数据处理的重要一环。传统方法对孔洞区域包含多种曲面的孔洞,修补方法会产生失效或修补效果不理想的情况。本文引入了切片方法来进行复杂孔洞的修补,并在此基础上使用双向切片方法,修补的效果及精度良好。

Research about Point Cloud Hole-repairing Based on Bidirectional Slice Method |
| |
| Abstract: | Patching the point cloud holes is an important part in the point cloud data processing.The result of the hole-repairing is unsatisfactory or useless when we use the traditional method to repair the hole which includes a variety of surfaces.Aim to solve this problems, this paper introduces the slice method to repair the complex holes.And introduce the Bidirectional slice method based on the slice method.The result of the Bidirectional slice method is good. |

| Keywords: | hole-repairing determine the hole boundary bidirectional slice projection and fitting |
