Abstract: A fast recog/ition algorilhm based on the geometric characteristics of a target was proposed to pursue the fast an adgurate reCognition for the spacecraft target, In the algorithm, a target incor-porated with linefran
sircylar patterns was designed to facilitate the accurate recognition.The noises d
in the images were rgduced y mean of a Gaussian filter. The object edges were detected by Canny op erator and te sequqce of edges were obtained by the single pixel tracking method. Then, the non-
xcaded according to whether the four non-collinear points were located on the
circular edgewere-s
same cjrcle & nt and the circle detection was implemented by the geometrical property that two dif-ferenarcsonthe
same circle have the same center and radius. Finally, the interruption was elimina-
tegby the &eometric relation between target circle and line, and the target was recognized precisely.
