Embodiment Construction
[0008] The first step is to use CCD to build a camera system, and fix a common precision gyro in the direction of the center of gravity of the camera system and the direction of the main optical axis;
[0009] The second step is to start the camera system, record an image as a reference frame image and divide the image into macroblocks according to the block matching algorithm, and start collecting gyro data in the horizontal and vertical directions at the same time;
[0010] In the third step, the camera system records an image as the current frame image and divides it into macro blocks, and divides each block into four quadrants, and ends the gyro data acquisition at the same time;
[0011] The fourth step is to use the gyro data between two frames to calculate the horizontal and vertical jitter offset of the camera system, and estimate the quadrant to which the jitter refers;
[0012] In the fifth step, in each macroblock of the current frame, the center point of the quadra...
