摘要(Abstract)：

针对影响航空摄影测量精度、作业效率和成像质量的各种因素,该文提出了内外方位元素可清晰分离的航摄仪检校场建设方法,实现了航摄仪内方位元素的高精度检校。以此为基础,设计和实践了一种满足现有航测生产要求的高性能宽角航摄仪,该设备具有旁向视场角超过80°、稳定曝光频率2Hz、自动感知飞行速度和地形高、依摄影测量规则自动决定曝光间隔等能力。数万平方千米的生产实践表明:宽角航摄仪影像色彩自然,全局纹理清晰,支持在大速高比环境下航空摄影,其综合作业效率超过当今国际品牌航摄仪2倍以上。

关键词(KeyWords)： 宽角航摄仪;大速高比成像;立体模型精度;航摄效率;航摄影像质量
