中文摘要：

接缝线的自动生成是遥感图像镶嵌处理中的一个关键步骤，也是数字正射影像图（DOM）产品生产的关键环节之一。由于接缝线与镶嵌图像中地物的完整性和色彩一致性密切相关，接缝线的自动生成直接决定着图像镶嵌处理的质量和效率，因此一直是国内外众多学者的研究热点。介绍了接缝线自动生成的原理，系统总结了基于重叠区影像差异的方法、基于同名点的方法、基于辅助数据的方法和基于形态学的方法等4类接缝线自动生成方法，对比分析了这些方法的优缺点，并展望了进一步优化接缝线的前景。

英文摘要：

Automatic generation is a critical procedure in remote sensing image mosaicking and a key technique for producing digital orthophoto map （DOM）. The seamline is closely related to the object integrity and color consistency in the image, so the automatic generation of seamline determines directly the quality and efficiency of mosaic processing, which thus becomes a hot research topic both in China and abroad. In this paper, the authors described the relative principle of the seamline generation and made a summary of four methods for automatic generation of seamline, which included methods based on overlap area image difference, identical points, auxiliary data and morphology. The prospect of further optimizing the seamline is forecasted on the basis of comparing and analyzing the advantages and disadvantages of these methods.
