To obtain the vibration amplitude-frequency characteristics of a in-orbit space camera,a space camera vibration parameter detection method by using TDICCD mechanical assembly technique was presented.According to TDICCD mechanical assembly technology,the images of same scene were taken by a TDICCD overlapping area at different moments,then the images were compared by using gray projection algorithm to derive the relative offset.Finally,the offset data were fitted,and the vibration parameters of the space camera were obtained according to the fitting result.Experimental results show that frequency measurement relative error and the amplitude measurement absolute error are less than 0.5% and 1pixel respectively for the one dimensional single frequency vibration;and those are less than 3% and 2pixel respectively for one dimensional mixed frequency vibration.Moreover,for two dimensional vibration which are both single frequency vibration along and vertical to the scanning direction,the frequency measurement error and the amplitudemeasurement error are less than 1% and 2pixel,Respectively.Experimental results demonstrate the correctness of detection methods,reach the purpose of detecting vibration parameters without additional facilities except the camera structure,and provide a data base for the subsequent image restoration.
