The invention discloses a
space debris fast detection and positioning method based on a space-borne
visible camera, relates to the
space debris on-
orbit fast identification, matching and positioning method based on the space-borne
visible camera, and belongs to the field of
spacecraft guidance and control. The method comprises the steps:
numbering debris orbits in an image shot by the space-borne
visible camera through a communication domain detection method; identifying target geometrical characteristics, and saving the debris imaging
orbit geometrical characteristics; according to the
image acquisition time and the debris imaging geometrical characteristics, making an inter-frame matching criterion, carrying out inter-frame matching, and making the debris imaging orbits between frames correspond to one by one; and according to the inter-frame matching result, calculating a target
azimuth angles alpha and beta, and completing debris
azimuth angle positioning. The identification, matching and positioning of the
space debris imaging can be realized, and the high matching rate and the high positioning accuracy can be satisfied. In addition, according to the inter-frame matching result, ROI
region selection is performed, the calculation efficiency of the communication domain detection is improved, and the problem of limited calculation resources on a star can be solved.
