Improved quadric surfaces recognition from scanned mechanical models

引用

Computer Aided Drafting,Design and Manufacturing 2016年第4期26卷 9-19页

作者： Quan Weize Guo Jianwei zhang xiaopeng Yan Dongming National Laboratory of Pattern Recognition Institute of AutomationChinese Academy of SciencesBeijing 100190China University of Chinese Academy of Sciences Beijing 100049China.

This paper presents a novel algorithm for identifying quadric surfaces from scanned mechanical models. We make several important improvements over the existing variational 3D shape segmentation framework, which utilizes Lloyd＇s iteration. First, instead of using randomized initialization （which likely falls into non-optimal minimum）, the RANSAC-based initialization approach is adopted. Given a good initialization, our method converges quickly than previous approaches. Second, in order to enhance the stability and the robustness, we carefully modify the distortion-minimizing flooding algorithm by using seed regions instead of seed triangles. Third, the geometric constraints are introduced into the optimization framework. The segmentation quality is further improved. We validate the efficiency and the robustness of our proposed method on various datasets, and demonstrate that our method outperforms state-of-art approaches.

关键词： shape segmentation quadric surfaces geometric constraints Lloyd's iteration

多年以来,公共博物馆围绕着对藏品的保管、处理和利用建立了一套行之有效的组织结构,维持和发展了博物馆对社会产生影响的力量。随着信息技术的广泛应用,博物馆面临着信息大量涌现和社会需求多样化、迅捷化的转变,这种刚性组织的适应和应对能力开始出现下降。本文从柔性组织的原理和博物馆信息处理的本质和流程分析入手,提出通过建立全面的柔性信息系统的方法来促进博物馆组织向着柔性组织方向发展,避免目前行政管理体制下调整组织结构的困境,提升博物馆影响和改变社会的能力。

A novel method of initiating nuclear fusion reactions in a full plasma environment was suggested, and a proof-of-concept experiment was carried out with the D ＋D → n＋3He reaction. In this new approach, two plasma jets generated by high-intensity lasers collide headon-head. The center-of-mass energy of the nuclei increases accordingly, and therefore, reaction products can be significantly enhanced, especially in the sub-Coulomb barrier ranges. As a result of the fusion reaction, up to - 7.6 ×105 neutrons had been observed. This new type of ＂plasma collider＂ could provide an innovative tool to study nuclear reactions under astrophysical conditions.

本研究采用启动词汇判断任务考察语言分布信息对英语母语者和中国大学生搭配加工的影响。结果显示:(1)在正向启动词汇判断任务中,英语母语者对右向和左向搭配的加工均有启动效应,但对右向搭配的启动量更高;大四英语专业学生仅对右向搭配的加工有启动效应。(2)在反向启动词汇判断任务中,英语母语者对右向和左向搭配的加工均有启动效应,但对左向搭配的启动量更高;大四英语专业学生仅对左向搭配的加工有启动效应。(3)大二英语专业学生在正向和反向启动词汇判断任务中均无启动效应。(4)搭配频率、词频和连接强度可显著预测英语母语者的启动量,而搭配频率和词频可显著预测大四英语专业学生的启动量。本文认为英语母语者和二语学习者的搭配表征均受语言分布信息的影响,并指出方向偏好是考量搭配加工的一个重要变量。
