摘　　要：针对线阵CCD影像,分析了GC3多视匹配模型,引入了MVLL多视匹配模型。研究了GC3与MVLL多视匹配模型的工作过程,综合比较了两种模型的异同。利用ADS40影像,针对相似、遮挡特征,做了多视匹配试验。结果表明,多视匹配模型能够综合利用多张重叠影像信息,提高匹配可靠性,具有较高的匹配优势。Aimed at the matching of line-array CCD imagery, GC^3 multi-view matching model is analyzed, and meanwhile, MVLL multi-view matching model is introduced. After an analysis of working procedure of GC^3 and MVLL multi-view models, similarities and differences of the models are compared. Based on ADS40 images ,multi-view matching experiments were done on both similar and occluded features. The experimental results prove that the models can synthesize a great number of overlapping images to enhance matching reliability, and thus, possess great matching superiority.
