摘要
国产大像幅数码相机应用于航空摄影测量是目前摄影测量界关注的焦点,为此我们采用国产SWDC-4四拼航空数码相机,利用其幅面大、分辨率高、基高比大、不受阴天天气条件约束等优势,结合项目需求进行了石莱河河道影像获取,利用航天远景公司生产的DatMatrix2.0空三处理软件对影像数据进行空三加密处理,利用MapMatrix4.1软件进行内业立体DLG数据采集,以验证其可行性。本文结合工程应用实例验证了SWDC-4相机在河道测量应用中的可行性。本相机的应用填补了国产航空数码相机的空白,加快了我国航空摄影测量内外业一体化的进程。
Large format digital aerial camera produced in China using in the production attracted the most focus from the field of present photogrammetry.Combining the project demand and the advantage of this camera,such as large format,high resolution,good Base-height ratio.Without engagement of cloudy,we capture digital images of SWDC-4 of Shilai River.Using DatMatrix 2.0 to realize aerial triangulation,and using MapMatrix4.1 to capture DLG data.Combining the project,the test result shows that the surveying precision of SWDC meets the demand of the topographic survey with the scale of 1 ∶2 000.The use of our camera,fills up the empty in our country,accelerates integration of indoor and field of photogrammetry in our country.
