中文摘要：

现在航空摄影测量技术两极化日趋明显,以微软UCX、LEICA ADS、Z/I DMC为代表的大幅面相机的成图质量在高空航空摄影测量市场已居领先地位.近几年无人机航测发展迅猛,其成本低、操作灵活等优势已使低空成图市场竞争激烈.中幅面航空摄影测量将作为现阶段中高空航测市场的重要补充,其兼具低空无人机的灵活性和高空大幅面相机的成像精度,中幅面航空摄影测量系统的集成成熟度将决定其工程使用价值和市场格局.

英文摘要：

Now, we see a technology of polarization obviously on aerophotogrammetry. MicroSoft UCX, LEICA ADS and Z/I DMC leads the high altitude aerophotogrammetry, because of leading edge technology. In recent years the UAV is developing rapidly, low-cost and flexibility of operation have made the market competitions unprecedentedly intense. As an important supplement to medium-altitude, medium format aerial camera system have both flexibility of UAV and imaging accuracy of large format aerial camera. The integration maturity of medium format aerial camera system will determine its engineering application value and market pattern.
