一种多摄像机全景视频图像快速拼接算法

针对多摄像机全景成像系统在近距离观测时全景图像存在视差失真和拼接费时的问题,提出了一种自适应调整相邻图像间变换矩阵的快速拼接算法。算法根据相邻图像重叠区域的匹配程度,采用快速自适应优化调整算法确定最佳变换矩阵参数,从而实现全景视频图像的无缝拼接。实验结果表明:本文提出的算法可以快速实现多摄像机全景视频图像的光滑拼接,满足近距离全景视频观测的实际要求。

A fast mosaicing algorithm for multi-camera panoramic video images

To overcome the parallax distortion and time-consuming problems encountered in multi-camera panoramic imaging system during short distance observation applications,this paper presents a fast mosaicing algorithm based on adaptive adjustment of the image transformation matrix between adjacent images.According to the matching degree of overlapping image area,the proposed method uses fast and adaptive optimization algorithm to search the optimal parameters of transformation matrix that can minimize the parallax distortion,thus realizing real-time and seamless mosaicing of panoramic video.The experimental results show that the proposed algorithm can construct multi-camera panoramic video seamlessly and meet the real-time requirement for panoramic video observations at short distance.
