An Electronic Image Stabilization Algorithm Based on Improved FAST Feature Point Matching

Aiming at the problem that the video picture of the dispatch terminal of the public network digital trunking system is rotated and jittered, which affects the judgment of the command and dispatch personnel, this paper proposes an electronic image stabilization algorithm based on improved FAST feature point matching. The algorithm combines the SAD feature matching algorithm to match the feature points extracted from the current frame and the reference frame, and uses the improved RANSAC algorithm to eliminate the mismatch of feature points, thereby obtaining an accurate matching image. Theoretical analysis and experimental results show that, compared with the traditional algorithm before the improvement, the algorithm proposed in this paper can improve the accuracy of feature point matching in video images with low latency.
