摘要
在机载IRST对地面目标的搜索跟踪过程中,由于飞机自身的运动,机载IRST获取的红外图像中包含了目标及复杂的地面运动背景。为克服图像序列中地面运动背景对目标跟踪的影响,在图像预处理算法的研究中,通过对机载IRST稳定平台下背景与目标的图像运动特点的分析,提出了一种基于帧间运动估计的背景抑制算法。
On the searching and tracking of ground targets,the images captured from the airbased IRST are composed of targets and complicated moving surface background, because of the selfmovement of the airplane. A background suppression algorithm based on interframe motion estimation is proposed to overcome the influences of moving surface background to the target tracking,according to the study of movcmetlt characters of background and targets in the image list captured from the airbased IRST stabilization platform structure.
