基于POS系统的无人机遥感图像融合方法的研究与实现
|
摘要
根据无人机遥感图像像幅小、几何畸变大、图像配准精度低等特点,提出采用最佳缝合线融合方法对无人机遥感图像进行融合。试验对30张无人机遥感图像序列进行了融合测试,结果表明这种融合方法能够很好地应用到无人机遥感图像的融合中,不仅可以有效地消除拼接线,而且能够避免"鬼影现象",使合成图像的整体目视效果得到了大幅提高。
Since UAV remote sensing images have the characteristics of small picture,large geometric distortion,and low precision images registration,this paper proposed to adopt the method of the optimal stitching line for UAV remote sensing images fusion.In the experiment,30pieces of UAV remote sensing image sequence were tested,and the result showed that the method is effective for UAV remote sensing image fusion,which can not only eliminate splice line,but also avoid the"ghost phenomenon".
