摘要
采用基于GPS辅助空中三角测量的摄影测量方案,以四川宜宾摄区为例,设计3种比例尺,验证SWDC在国家基础测绘中各种比例尺尤其是四川等特殊困难地区的使用情况,并实现SWDC从地面设计、空中自动拍摄到室内成图的全过程,为形成一套完整的数码航空摄影测量可行性操作规程奠定技术基础。
The photography survey program is adopted because of GPS-supported triangle survey, and Yibin photographic area in Sichuan is taken as an example in designing three kinds of ones to verify all kinds of scales of SWDC in the national foundation survey, and especially in the particular difficult areas, such as Sichuan Province. And besides, carrying out the complete process of SWDC that related to the ground design, the airborne automatic photography and the interior manufacturing maps are realized, and the technology foundation for the feasibility of a set of complete digital aerial photography survey is laid.
