摘要:
在三维激光SLAM中,激光里程计的求解精度对建图精度有着至关重要的作用。为定量分析前端激光里程计中点云匹配方法的效率和精度,本文根据2种不同的点云匹配方法:迭代最近点ICP,正态分布变换NDT,搭建了前端激光里程计,并分别在KITTI数据集上进行了仿真实验,得出了绝对位姿误差和相对位姿误差,结果表明NDT算法精度和鲁棒性均高于ICP算法,且NDT算法适用于粗匹配,ICP算法适用于精匹配。

摘要:
提出一种基于采样一致性初始配准(SAC-IA)和正态分布变换(NDT)配准融合的点云配准方法.首先计算出待配准点云和目标点云的快速点特征直方图(FPFH)特征;然后依据该特征,利用SAC-IA算法求出初始转换矩阵,完成初始配准;最后在初始配准的基础上,利用NDT算法对两片点云进行精配准.实验结果表明,该方法的配准精度显著优越于ICP算法,且配准效率也有所提升.

摘要:
针对船舶企业焊缝无损检测(Nondestructive Testing,NDT)的问题,提出NDT信息化管理的必要性.通过焊缝库维护、焊工管理、NDT报验申请、检测结果录入、焊缝自动追踪和数据统计分析,实现对焊缝生命周期的追溯,可有效解决船舶企业手工管理NDT产生的信息分散混乱、无法追溯等弊端.

摘要:
Background: Bobath method was initially applied in adults and then in children with cerebral palsy. Studies conducted in recent years have shown that the NDT-Bobath method improves function and mobility among persons with Multiple Sclerosis (MS) and Hemiplegia. Purpose: The purpose of the present study was to investigate the effect of NDT-Bobath method in the mobility of patients with neurological disorders (hemiplegia, multiple sclerosis), as evaluated using the TUG, BBS, TMT, and MAS tests. Methods: The study included 20 persons with neurological disorders (11 persons with multiple sclerosis and 9 persons with hemiplegia). The mean age of the participants was 38.7 ± 13.9 years and mean body mass was 65.1 ± 13.1 kg. The participants in the two groups Low Frequency (LF) and High Frequency (HF) followed two different intervention Bobath-NDT programs in terms of frequency. For the statistical analysis a two-way repeated measures analysis of variance (ANOVA) was performed. Results: Bobath-NDT method improves both mobility and functionality of patients with neurological disorders (BBS, p = 0.095 and Tinetti test, p = 0.099) but did not improve spasticity according to the results of MAS scale, p = 0.095. Conclusions: Overall, the results of the present investigation provided considerable evidence suggesting that Bobath-NDT method improves mobility according to the tests (BBS, TMT), but did not improve spasticity according to the results of MAS scale. Therefore, it was concluded that Bobath-NDT method improves both mobility and functionality of patients with neurological disorders. More researches will have to be done in the future.

摘要:
The purpose of the present study was to examine the effectiveness of the NDT method (Bobath) in children with CP. Twenty children with cerebral palsy (7 with quadriplegia, 6 with diplegia and 7 with right hemiplegia), with mean age of 4. 85 ± 2. 49 years, took part in the study. Materials-Method: The children participated in an intervention that consisted of an 8-week Bobath program. GMFM-88, PEDI and TUG scores were measured across three time points during the intervention (a baseline measurement, a second at the end of the intervention and a post-intervention measurement one month after the end of the intervention). Results: The results of the NDT intervention showed that the participant children significantly improved their GMFM-88 and TUG scores between initial and final measurement and maintained this one month later (F2,36 = 69,778, p 0.001), while in PEDI the intervention program had no statistically significant effect (F2,36 = 0.844, p = 0.438). In conclusion, there is strong evidence of the effectiveness of the NDT (Bobath) method in improving the mobility of children regardless of the frequency of its application.
