区域级倾斜摄影数据高效获取方案——以实景三维山东为例

Efficient data acquisition scheme for area-level oblique photography——Taking real-life 3D Shandong as an example

面对大规模实景三维航空摄影的测量需求,亟须设计效率更高、灵活性更强的倾斜影像获取方案。为验证SWDCMax6-Ⅱ型航摄仪的可靠性、高效性、灵活度与其他优势,文章以栖霞市为测试场景开展了航摄对比试验,针对航摄效率、生产成果等进行了对比分析。结果表明,与Ⅰ型航摄仪相比,Ⅱ型航摄仪的影像质量、模型效果均无差异,且模型结构在某些三维场景下更为完整,效率提升了25%,在保证成果精度的前提下能大幅降低数据采集成本。

Faced with the measurement needs of large-scale real-life 3D aerial photography,there is an urgent need to design a more efficient and flexible oblique image acquisition scheme.To verify the reliability,efficiency,flexibility,and other advantages of the SWDC Max6-Ⅱaerial camera,this article conducted aerial photography comparative experiments in Qixia city as the testing scenario,and compared and analyzed the efficiency and production results of aerial photography.The results show that compared with the TypeⅠaerial camera,the TypeⅡaerial camera has no difference in image quality and model effect,and the model structure is more complete in some 3D scenes,with an efficiency improvement of 25%.It can significantly reduce data acquisition costs while ensuring the accuracy of the results.
