多基线立体影像的GC3-P-SGM匹配方法

摘要

以“几何约束互相关”模型为基础,将迭代高程等效成“半全局影像匹配”方法中的左右视差,通过匹配代价的聚合分析,提出了一种多基线立体影像匹配方法GC3-P-SGM,并给出了其具体匹配步骤和处理流程。利用天绘一号卫星影像数据进行了实验和分析,结果表明,该方法具有较高的匹配性能和匹配精度。%Based on Geometrically Constrained Cross-Correlation Model( GC3 ) , of which the iteration height is e-qualized as the x-parallax of Semi-Global Matching Method( SGM) , a new multi-baseline matching method GC3-P-SGM was proposed by aggregation of the computed matching cost. The matching steps and processing process of the method were given. Experiments were done on Tianhui satellite imagery, and the experimental results proved that the method was of great matching performance and high matching precision.
