| 摘 要： | 点云数据的曲面重建就是对扫描设备获得的物体散乱数据点重建三维物体表面,它被广泛应用于计算机动画、目标识别、数据可视化以及地理信息系统。点云的隐式曲面重建由于能够去除点云噪声,修补孔洞和裂缝,不需要拼接和平滑等后续处理,成为点云数据集曲面重构的重要方法。文中综述了目前一些主要的隐式曲面重构方法,就隐式模型以及相应的曲面重构算法的优缺点进行了分析比较,并对隐式曲面重构存在的问题和未来发展方向作了相应的分析和讨论。

| Abstract: | The surface reconstruction of point cloud data is to reconstruct the surface of 3D objects on the scattered data points of the scanning equipment.It is widely used in computer animation,target recognition,data visualization and geographic information system.The surface reconstruction based on implicit function is an important method of surface reconstruction of point cloud datasets due to its ability to reconstruct holes and cracks,and then do not need splicing and smoothing.This paper summarized some main implicit surface reconstruction methods,analyzed and compared the advantages and disadvantages of implicit model and corresponding surface reconstruction algorithm.Finally,the existing problems and the future development direction of implicit surface reconstruction were analyzed and discussed. |
