摘　　要：球面全景图技术是一种基于图像配准和拼接的技术,主要利用的是光学图像构建数据模型绘制虚拟场景,相比传统的三维建模绘制,其主要的优势表现在效率和效果上。近年来,球面全景图技术随着无人机技术和航拍技术的发展有了更大的应用平台,同时,更多相关的研究,如基于图像绘制的图像配准和拼接技术也将进一步受到重视。通过无人机拍摄获取图像,对拍摄的多张图像使用SIFT或SURF算法来提取图像中的特征点,同时,对这些特征点进行初步计算匹配时加入序贯相似性检测算法,由此完成图像拼接工作。通过研究和实验证明,采用算法既能提升匹配速度,又能得到较好的无缝拼接效果图。Spherical panorama technology is a technology based on image registration and splicing.It mainly uses optical image construction data model to draw virtual scenes.Compared with traditional 3D modeling,the main advantages are in efficiency and effect.In recent years,spherical panorama technology has become a larger application platform with the development of drone technology and aerial photography technology,and more related research, such as image registration and image stitching based on image rendering,will be further emphasized.The image is acquired by the UAV,and the SIFT or SURF algorithm is used to extract the feature points of the image. At the same time,the sequential similarity detection algorithm is added to the preliminary calculation of the feature points,thereby completing the image mosaic.jobs.Through research and experiments,it is proved that the algorithm can improve the matching speed and get a better seamless mosaic effect picture.
