Ultra-high-speed impact fragment cloud modeling and damage assessment method based on image processing

Abstract

The invention provides an ultra-high-speed impact fragment cloud modeling and damage assessment method based on image processing. The method comprises the following steps of: firstly, carrying out noise reduction processing and fragment segmentation on a fragment cloud picture; performing feature point extraction and feature point matching on the segmented fragment cloud picture to complete fragment matching of two continuous frames of fragment cloud pictures; and finally, carrying out motion track modeling on the matched fragments, comparing the characteristics of the fragments in the two groups of fragment cloud images, and evaluating the damage condition of the rear plate according to the characteristics of the fragments. According to the method, the fragment information obtained by theimage processing technology can be fully utilized, so that the damage condition of fragments to the rear plate is effectively evaluated, and more effective information is provided for improvement ofthe protection structure of the ultra-high-speed impact spacecraft.

Description

technical field [0001] The invention belongs to the field of image processing, in particular to an image processing-based ultra-high-speed impact debris cloud modeling and damage assessment method. Background technique [0002] With the increase of human spaceflight activities, the space debris environment has deteriorated sharply in recent years. Countries have paid more and more attention to the design of debris protection structures for spacecraft, especially manned spacecraft and space laboratories. This engineering background has greatly promoted the impact of thin plates on ultra-high speed. And the resulting debris cloud research work. Many scientific research institutes and universities in the world have conducted research on this issue, and there is an international conference on hypervelocity impact every two years. In China, a special project on space debris of the National Defense Science, Technology and Industry Bureau has been established to promote research on...
