遥感侦察是侦察测绘领域的重要手段,而对于遥感图像的分析融合又是遥感侦察的主要内容之一,本文针对遥感图像融合中的多遥感图像全景拼接问题进行分析,讨论了梯度域方法在这方面的应用,并给出了一种消除图像拼接接缝的方法,梯度场整体变分(Gradient Field Total Variation,GFTV)方法。分析并讨论了该方法的性质及实现方法,并将该方法用于遥感图像融合拼接,将该模型与当前常用的几种融合模型进行了理论和实验上的讨论和比较,表明了GFTV模型的优势。
Remote sensing reconnaissance is an important method in the field of reconnaissance and mapping, and the analysis and fusion of remote sensing images is one of the main contents of remote sensing reconnaissance. In this paper, we analyze the multi-remote sensing image mosaic in remote sensing image fusion and discuss the method of gradient domain And gives a method to eliminate the image mosaic joint and the Gradient Field Total Variation (GFTV) method. The properties and implementation methods of this method are analyzed and discussed. The method is applied to remote sensing image fusion and splicing. This model is discussed and compared theoretically and experimentally with several commonly used fusion models, which shows that the GFTV model Advantage.
