Discussion on Application of Differential Geometrical Quantity in Estimating Point Cloud Model

在三维数字扫描技术与设备发展的过程中,点云模型备受学术界与工业界的重视,点云模型被广泛应用到数字娱乐、医学辅助诊断、航天模拟与工业设计中.估计点云模型微分几何量是指在研究计算机图形学、数字几何处理、计算机视觉中的主要问题,对于点云模型微分几何量估计的离群点问题,可以对现有曲率与法向估计的方法进行改进.因此,文章就对估计点云模型微分几何量应用进行分析.

In the process of the development of 3D digital scanning technology and equipment,the point cloud model has received much attention from academia and industry.The point cloud model is widely used in digital entertainment,medical aided diagnosis,aerospace simulation and industrial design.Estimating the differential geometry of the point cloud model refers to the main problems in the study of computer graphics,digital geometric processing,and computer vision.For the outlier point estimation of the differential geometry of the point cloud model,the existing curvature and normal can be estimated The method was improved.In this way,this paper analyzes the application of the differential geometry of the estimated point cloud model.
