[0026] The present invention will be further described below in conjunction with the drawings.
[0027] Step 1. Select the reference frame and read in the current frame.
[0028] In order to eliminate the shift and rotation of the image caused by the jitter of the camera system, and realize the stability of each frame of the image on the camera system, it is necessary to select a stable image from the video image that the camera system is shooting, and treat it as image stabilization Reference frame for translation and rotation in the middle. The video image sequence being shot is read into the image stabilization system one by one in order of one after another, as the current frame to be stabilized.
[0029] Step two, image binarization.
[0030] In the video image of the navigation process, the sea and the sky occupy most of the area, and the gray scale of the sea and the sky have obvious differences. The method of image binarization is used to enhance the gray scale difference bet...
