摘　　要：随着军事技术的不断发展,各个国家对精确打击武器迫切需求,开展关于景像匹配技术的研究具有重要意义。一般图像匹配的实时图和模板图是在不同天气、不同时间、不同角度以及不同成像设备的条件下获得的,所以图像之间会存在明显的畸变,因此论文提出了一种基于尺度不变的景象匹配技术方法。首先是利用SURF特征提取对实时图和模板图进行配准,然后对感兴趣的目标进行模板匹配,实现景像匹配。论文方法不仅对于各种畸变和变换有很好的鲁棒性,也能够对不同目标进行模板匹配,实现了景像匹配的实时处理。With the continuous development of military technology,various countries have an urgent need for precision strike weapons. It is of great significance to carry out research on scene matching technology.General image matching real-time image and template image are obtained in different weather,different time,different angles and different imaging equipment condition,so the image will exist between the obvious distortion,therefore this paper proposes a method of scene matching technology based on scale invariant.First,SURF feature extraction is used to register real-time images and template images,and then template matching is carried out for interested targets to achieve scene matching.The method in this paper is not only robust to various distortion and transformation,but also capable of template matching for different objects,so as to realize the real-time processing of scene matching.
