摘要

本文提出一种针对球面虚拟实景底部空洞的快速修复算法

首先获取球面全景与球面虚拟实景间映射关系

并基于不同时刻球面虚拟实景间的空间位置关系建立位置映射模型

然后通过求解得到不同时刻球面全景之间的对应关系并实现缺失部分的修补

最后通过对修补区域亮度的调整及边缘融合

对修补结果进行优化.理论分析和实验结果均表明

该方法利用底部空洞位置固定这一特点建立复杂度仅为O(n)的修补算法

能够快速有效的实现球面实景底部空洞的修复.

Abstract

A fast repairing algorithm is proposed especially for the bottom hollow existing in spherical virtual image (SVI).First

the mapping relationship between spherical panorama and the corresponding SVI is acquired

and the location mapping model is constructed based on the relationship of different SVIs obtained at different moments.Then

the correspondence between different spherical panoramas is solved and the missing parts are repaired.At last

through luminance adjustment and edge blending

the repairing result is optimized.Theoretical analysis and experiment results show that

through using the feature of bottom hollow's fixed location

a fast repairing algorithm is built with the complexity of

(

)

which can realize the repairing of bottom hollow in SVI quickly and effectively.
