摘要
数字摄影测量中单立体影像匹配可能获取"病态解",匹配可靠性低、成功率不高,限制后续产品生产。在ADS40物方多视匹配模型基础上,给出了像方多视匹配AMMGC模型,该模型综合利用多张影像信息,减小信息盲区,获取匹配点的"确定解"。AMMGC模型利用匹配检查策略检验匹配结果,通过自适应窗口变换策略选取最佳大小与形状的匹配窗口,进一步提高匹配精度与成功率。实验结果表明:该模型匹配成功率高,能够可靠匹配相似特征点和地表不连续特征点,具有较强的实用性。
In digital photogrammetry, single stereo image matching models, which may obtain multiple solutions, have low matching reliability and successful rate. And therefore, subsequent productions are greatly constrained. Based on ADS40 object-based multiple-image matching model, image-based AMMGC multiple-image matching model was given. AMMGC model was appropriate for the matching of three-line-array digital images, synthesized all the matching images＇ information to avoid blind information area, and obtained a single solution. It checked matching results by image checking strategies and optimized image matching results by adaptive window growth schemes. Experiments results proved that AMMGC model could obtain reliable matching results, reliably match similar feature points and discontinuous feature points, and thus possess good practicability.
