| 摘 要： | 针对视频图像中存在的平移抖动和旋转抖动,提出了一种基于灰度投影和模板匹配的电子稳像方法。用网格法搜索图像中灰度特征明显的区域,结合分象限法提高系统的鲁棒性,在不同坐标系下分别投影,纠正平移和旋转偏差。给出了模板制作方法和配准步骤。实验证明,该方法具有较高的精度和很高的处理速度,能够实时去除由视频图像抖动引起的噪声。

| Abstract: | Aiming at the rotational and translational motion among video images,an electronical image stabilizing method is discussed based on gray scale projection and pattern matching.Using the method of search according to girding to find image blocks which have outstanding gray scale features,quadrants are set to improve the robust quality of the system,projection is made in different ccordinate frames to correct the planar and angular shift respectively.Steps of pattern making and image regis- tration are given.It has been proved by experiments that this method is of high accuracy and speed,being able to removed nois- es produced by motion among video images in real time. |
