摘　　要：针对全方位图像扭曲,不利于人眼正常观察的问题,提出一种基于Hough变换的全方位图像快速展开算法。该算法首先通过Hough变换检测场景圆心及半径,然后根据半径确定展开图像的大小,最后基于圆心对图像进行展开。实验结果表明,这种算法能够快速有效实现全方位图像的展开,且减少展开图像的失真,为后续研究奠定基础。The main problems of the omnidirectional vision system are distorted and not suitable for human observation,therefore a fast image unwrapping algorithm for omnidirectional images is brought forward based on Hough transform.Firstly,Hough transform algorithm is used to detect the center and radius of the scene,the unwrapped image size is determined by the radius of the scene circle.Finally,the image can be unwrapped based on the center of the circle.The experiment results show that the proposed algorithm can ...
