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-Ⅱ aerial 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 Type Ⅰ aerial camera， the Type Ⅱ aerial 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.
