【摘要】 由于理论上全景图像柱面展开算法比较复杂,在系统中占据的时间开销非常巨大,并且在展开过程中需要知道摄像头的焦距,镜头的双曲面方程等内参数,以及与相机位置关系等外参数,而这些参数在某些系统中不是固定不变的,所以理论上全景图像柱面展开方法在真实的系统中是很难应用.在介绍全景图像理论柱面展开算法的基础上,对该算法进行了优化,并对这2种算法进行了比较.实验表明采用该改进算法满足了实现实时处理的要求.更多还原

【Abstract】 cylindrical theory’s unwrapping algorithm for an omni-directional image is very difficult to use in practice,because it is rather complex,takes too much time,and needs the parameters of the hyperboloid mirror and the camera’s position.This paper introduces the theoretical unwrapping algorithm for omni-directional image,and proposes an approach to simplify this algorithm,and optimizes the fast unwrapping algorithm.The paper also compares these two algorithms.According to the experiments the fast unwrapping algorithm meets the demand of the real-time system.更多还原
