High-speed video measurement method for moonlet flutter

The invention relates to a high-speed video measurement method for moonlet flutter. The method comprises the following steps: 1) constructing a high-speed video measurement system; and 2) shooting the vibrating moonlet through a high-speed camera, carrying out tracking matching and three-dimensional reconstruction on a target point pasted on the surface of the moonlet to obtain a time-history displacement curve of the target point, and calculating according to the displacement to obtain the flutter frequency of the moonlet. Compared with the prior art, the method has the advantages of simplicity, accuracy and the like. 本发明涉及一种小卫星颤振高速视频测量方法，包括以下步骤：1)构建高速视频测量系统；2)通过高速相机对振动的小卫星进行拍摄，通过对粘贴在小卫星表面的目标点进行跟踪匹配和三维重建，获得目标点的时程位移曲线，根据位移量解算得到小卫星的颤振频率。与现有技术相比，本发明具有简单精确等优点。
