摘要
主要研究基于单片调绘矢量数据的正射纠正模型与思路,基于单片调绘矢量数据如何有效快速正射纠正是阻碍单片影像直接应用于测绘生产的主要原因。通过试验发现,单片调绘的矢量数据经过正射纠正后完全满足1∶10 000 DLG测图精度要求,可以直接作为矢量数据成果转入内业编辑工序,不再仅仅作为内业定性资料使用,省去了作业人员重新绘制矢量数据的多余生产环节,有利于提高1∶10 000DLG数据生产效率,为丰富航摄内外业一体化测图生产提供了重要技术支撑。
The model and methods of ortho-rectification based on single-map surveying and mapping vector data has been studied in this article.But how to manage to do is the obstacle during surveying and mapping.After several different experiments,we found that the data from single-map surveying and mapping ortho-recitification can meet the requirements of 1 ∶ 10 000 DLG mapping accuarcy,and can be used as vector data results,which has simplified the interior work procedure by avoiding redrawing vector data,improved the efficient of 1 ∶ 10 000 DLG data production and provided important technical support for integration of indoor and outdoor aerial survey.
