摘　　要：针对大面阵相机成像特点,分析提出了在高分辨率对地观测条件下航天测绘应用的两种立体探测模式,即高分辨率交向立体摄影测量模式和小基线立体摄影测量模式。分别对两种模式的基本原理进行了阐述,分析了各自存在的优势和不足,以及主要的应用方向。通过理论和仿真分析对两种应用模式进行了原理验证。最后对大面阵相机航天立体测绘两种模式的应用特点进行了对比,指出了进一步研究的方向。According to the imaging characteristics of large plane array digital camera, the two stereo modes of space photogrammetry were advanced on the status of high resolution exploring earth surface, viz, high resolution stereo photogrammetric mode and small base vision stereo photogrammetric mode. The fundamental of two modes was described, the advantages and the shortages were analyzed, and the main applications were proposed. The two modes were tested theoretically by emulational images. In final, the application points of the two modes are contrasted, and the main researching aspects were proposed for the future.
