摘要	To obtain the amplitude-frequency feature of vibration of space camera during the camera shooting of rail, a kind of vibration parameter detection method of space camera based on CMOS self-correlation imaging of plane array of roller shutter was proposed. Based on CMOS imaging principle of roller shutter, for the continuous shooting of same photographic field, a group of image sequences with correlation were obtained. The images formed were compared through gray projection algorithm to calculate relative shift. The shift data was fitted, so that the vibration parameters of space camera were calculated according to fitting results. The confirmatory experiment shows that the relative error of cycle detection of two-dimensional vibration is no more than 2%, and the absolute error of amplitude detection is no more than 1 pixel. The experimental results indicate that this method may detect high-frequency vibration by taking advantage of low frame-frequency image sequence, so the data transmission and processing pressure of detection algorithm are produced by a large margin; It provides the possibility to realization of star embedded type of detection algorithm, and has good application to push-broom camera and staring camera. 2016, Science Press.
