Abstract

The results of the Sreda–MKS space experiment showed that visual data on the vibrations of the ISS structural elements allow one to acquire quantitative characteristics of these vibrations. Such characteristics were found as a result of the analysis of time series obtained by tracing some objects in the ISS structure on video sequences. The numerical data are the vertical and horizontal coordinates of the selected point of the structural element in the frame expressed in pixels. Analysis of the time series allows us to reconstruct the actual dependence of these coordinates on time. In some cases, this dependence is oscillatory in nature and can be represented as the sum of a finite number of harmonics, the amplitudes and frequencies of which are determined by means of spectral analysis.

基于视频信息的空间站结构单元振动研究

摘要

所述的结果Sreda-MKS空间实验表明，在的振动视觉数据ISS结构元件允许人们获得这些振动的定量特性。这些特征是通过对国际空间站中的一些物体进行追踪而获得的时间序列的分析结果发现的。视频序列的结构。数值数据是以像素表示的框架中结构元素的选定点的纵横坐标。时间序列的分析使我们能够重建这些坐标对时间的实际依赖性。在某些情况下，这种相关性本质上是振荡的，可以表示为有限数量的谐波的总和，其幅度和频率通过频谱分析确定。
