摘　　要：为适应中国不同地区、不同气候航空摄影测量的广泛需求,研制大面阵数字航摄仪.采用首创的室外超大型几何定标场精确标定相机相对方位元素,为影像拼接提供精确的相对外方位线元素和可靠地角元素初始值;并设计可更换镜头的灵活结构,使其具有方便检校、基高比大、高程精度高等相对于进口相机的独特系统优势.研制出国内首创大面阵数字航摄仪-SWDC,大范围应用于国家基础测绘、数字省区、数字城市、国土资源调查、应急救灾等领域,共完成70多万平方公里的航空摄影工作,有力推动中国数字航空摄影的发展.To meet the wide needs of aerial photogrammetry in different regions and different climates in China, it is necessary to invent digital airborne photogrammetric camera with larger plane array. Using outdoor super large geometric calibration field to calibrate camera of relative exterior orientation, invades precision relative exterior orientation of line and the initial value of accurate relative exterior orientation of angle. Design of a flexible structure with interchangeable lens which has a convenient calibration, based high, elevation accuracy higher compared with that of the imported camera unique system advantages. Digital airborne photogrammetric camera- SWDC with larger plane array which is firstly invented, is widely used in the national basic surveying and mapping, digital China, digital city, surveying land and resources, disaster relief and other fields, and completed a total of about 700,000 square kilometers of aerial nhoto^raDhv, nromoted Chinese digital aerial nhntn^rrnnhv
