Measurement and analysis of single video camera-system in clamp-band unlocking test

In the field of aerospace related experiments, the test of specific functional components is usually completed within a few seconds. Therefore, as one of the most intuitive optical measurement methods, the single video camera system, which can identify the dynamic characteristics of specific points in two-dimensional images is widely used, and the measurement effect is reliable and effective. Using the single video camera system, the maximum radial displacement of the clamp-band in the process of clamp-band unlocking is measured by using a single video camera system. And the influence of the space-arrow connection structure on the space-arrow separation is analyzed by judging the maximum envelope boundary of the clamp-band,
