全景图像柱面展开算法易产生块效应,影响展开图像质量。根据双曲面反射镜的性质和成像原理,分析得出了现有算法产生缺陷的原因,并给出了基于径向扫描的全景图像柱面展开算法数学模型。在径向扫描展开算法的拉伸过程中结合各向异性插值算法从而实现最终的算法,实验结果表明,新算法能够有效减少块效应,提高展开图像质量。
Nowadays
algorithm of unwrapping panoramic cylinder image is easy to produce the block effect
which reduces quality of expanded image greatly. According to the nature of the hyperboloidal mirror and the imaging principle
this paper analyzes the reasons for the defects of the existing algorithm
and gives a mathematical model based on the panoramic image cylinder radial scan unwrapping algorithm.The final algorithm is obtained combined with the unwrapping algorithm of radial scanning and the anisotropic interpolation algorithm. The experiments show that the new algorithm can effectively reduce the block effect and improve the quality of expanded image.
