Curvature Estimation of Cloud Data with Mass Scattered Points and its Computer Implementation
Abstract：The paper proposes a computer implementation of curvature estimation of cloud data with mass scattered points based on Matlab language.According to the features of cloud data distribution,cloud data with scattered points is divided into different areas.Adjacent points are approached by parametric quadric surface to calculate the normal vector of each point.Inconsistent normal vector is adjusted and the curvature of each point is calculated.Experiments show the method reduces the calculation of curvature of cloud data with scattered points.As a result,it can be realized on ordinary computers.
