Based upon the synopsis of electronic information system and system product assurance, this paper puts forward the process model and the product assurance framework of electronic information system, and sets forth a series of product assurance technologies, such as integrated design technology, Technology Readiness Level technology, system integration technology, software independent testing technology,...
Surface reconstruction based on Support Vector Machine (SVM) is a hot topic in the field of 3-dimension surface construction. But it is difficult to apply this method to cloud points. A reconstruction method based on segmented data is proposed to accelerate SVM regression process from cloud data. First, by partitioning the original sampling data set, several training data subsets and testing data...
Surface reconstruction based on Support Vector Machine (SVM) is a hot topic in the field of 3D surface construction. SVM based method for surface reconstruction can reduce the noise in the sampled data as well as repair the holes. However, the regress speed of SVM is too slow to reconstruct surface quickly from cloud points data set which has a lot of points. In this paper, a feature-preserved nonuniform...
A scattered cloud-point smoothing method based on surface feature is put forth by analyzing the surface local feature. The feature curvature proposed in this paper is a more accuracy parameter to present the contour of a surface. The method consists of three steps. Firstly, the normal of a point is estimated using covariance analysis. Secondly, the local surface is fitted through quadratic surface,...
