In order to identify the vibration parameters of a vibrated image, the principle and shortage of the traditional methods that based on image derivative and image transformation are analyzed, and a new parameter identification method is proposed afterward. By placing a high-speed CCD aside the master CCD, the vibration can be sampled accurately, and more information can be obtained for parameter identification. The series frames that captured by high-speed CCD are processed by gray projection algorithm and the vibration extents between adjacent frames along x and y direction are obtained. By using simple triangle operations, the vibration parameters can be identified, and the computational complexity of which can be reduced greatly. The experiment shows that the parameter identification method based on high-speed CCD can identify the parameters of vibration with any form accurately. The precise of parameter identification for linear vibration is less than 2.95%.
