摘要	In order to overcome image shakes in the video of the camera mounted on the aerial opto-electrical platform and to implement the image stabilization in real-time, a FPGA platform of real-time digital image stabilization (DIS) based on bit-plane matching was realized. Firstly, the local motion vectors were estimated by using Gray code bit-planematching. Then, the global motion vector was generated with a median filter method. Following that, a low pass filter was applied on the previous global motion vectors to get the current motion compensation vector. At last, the stabilized video was obtained by compensating the original one. A multi-bits concurrent matching method was proposed when estimating the local motion vectors using the bit-plane, which increased the parallelism of the FPGA and speeded up the matching velocity. The FPGA implementation of the function modules of video capture control, image buffering, motion estimation, motion filtering, and motion compensation were detailed out. The experiment results indicate that the proposed method can stabilize the 25 fps analog video with 720 576 pixelsin real-time, and can be applied in real-time applications.
