摘要
视频序列影像自动镶嵌是UAV视频影像处理应用中的基础环节和重要研究方向。针对序列影像镶嵌过程中,由于配准精度不高、误差累积所导致的拼接错位严重,镶嵌结果不理想的情况,从提高特征匹配的精度和准确度出发,提出了一种改进型的UAV视频序列影像自动镶嵌方法。通过对特征匹配结果的精细化处理,保证了影像配准的正确性,取得了较好的镶嵌结果。
Video image sequence automatic mosaicking was a basic part and important research direction of the UAV video image processing application. For the problems that wrong piecing together and imperfect mosaicking results, which arose from the imprecise registration and accumulation of error, the article presented an improved UAV video image sequence automatic mosaicking method that made betterment on both the precision and correctness of feature matching. Through the fine processing on the results of feature matching, it ensured the validity of image registration and got a preferable mosaicking result.
