摘要
轨迹降噪是计算机数据处理,尤其是时间序列有噪数据处理的重要研究内容.近年来,由于计算机应用水平的提高,在线处理对于轨迹降噪来说具有越来越重要的研究价值.该文基于Bernstein-Bezier曲线形式,提炼Bernstein-Bezier曲线光顺的特征模型,给出了在线降噪点AP(Action Point)的构建方法.基于Bezier AP给出了一种新的在线轨迹降噪方法.该方法构建简单、效率高而且推广性极强,实验证明了该方法是一种新颖有效的在线轨迹降噪方法.图2,表1,参5.
Noise reduction is an important research issue for computer data processing, especially for sequential data. In recent years, due to the fast development of computer application, the online noise reduction for the sequential data has become an increasingly important research focus. The paper based on Bernstein-Bezier curve formulation, distilled the feature model and proposed a novel noise reduction point-AP （Action Point） construction method. An online noise reduction method based on AP was then provided. Experiments prove that OBB curve is a novel online curve, and the online noise reduction with the OBB curve is feasible and effective. 2figs. ,ltab. ,5refs.
