基于改进SURF算法的实时视频拼接

Real-Time Video Stitching Based on Improved SURF

视频拼接可以广泛地应用在视频会议、视频监控等诸多领域,它可以在不降低分辨率的前提下扩大视野。然而由于它具有数据量大、环境复杂等特点,使得实时视频拼接成为一个研究热点。本文对实时视频拼接技术进行了研究。视频拼接的本质是图像拼接,首先介绍了图像拼接的一般流程、图像配准的含义,并对常用的图像配准技术进行了分析,确定了采用基于特征点提取、特征点匹配和图像融合的图像拼接方法。

Video mosaic is widely used in the fields of video conferencing, video surveillance and so on;it can increase the field of view while not reducing resolution. Due to large amount of data, complex environment and other reasons, real-time video mosaic becomes an active area of research. In this paper, technique of real-time video mosaic is studied.
