摘要 在分析、研究传统圆投影算法的基础上,提出一种扩展的圆投影算法用以解决传统圆投影算法引入的任意旋转角度景象匹配问题。该算法通过对匹配模版添加辅助点加以约束,可以实现旋转中心的准确定位,并且能快速准确地计算出旋转角度。实验表明,扩展的圆投影算法均能获得精确的匹配结果。 Based on analysing and researching original ring projection transformation algorithm,an extended ring projection transformation algorithm is raised which is used to solve the arbitrary angle rotation issues for scene matching.The proposed algorithm can not only fix the rotation center exactly,but also can compute the rotation angle fast and accurately by appending subsidiary restrict to the template.The experimental results demonstrate the accurate performance of this algorithm.
