摘要
正射影像镶嵌线羽化是正射影像镶嵌关键的一步,针对现有羽化方法存在的问题,本文提出一种基于泊松插值的镶嵌线羽化方法。采用没有匀色的正射影像进行实验,并与经典的线性加权法进行了对比。实验结果表明,本文方法相对于传统的线性加权法能更好地消除镶嵌线,起到提高正射影像色彩一致性的作用。
Orthoimage seam-line feathering is a crucial step in mosaicking orthoimages. Aim at the problems of the existing methods,this paper proposed a seam-line feathering method based on Poisson interpolation method. A block of orthoimages are employed to perform the experiment,and the results are compared to a result obtained from a classical linear weighting method. The results reaveal that the proposed method can eliminate the effect of seam-line better compared to conventional linear weighting method,and improve the consistency of color on final mosaic orthoimages.
