摘　　要：Pixel Factory利用POS数据,可减少对外业控制点的需求数量,实现高精度快速空三。但是目前,Pixel Factory的框幅影像加密成果,无法直接用于立体定向及数字线划图DLG数据的生产。本文利用Pixel Factory影像快速处理系统与IMU/GPS辅助的航空数码影像,提供Pixel Factory框幅影像加密成果在DLG生产中的应用方法,并用实际的生产数据进行试验,通过对数据的处理及精度检测,验证了本论文方法的可行性与实用性。Using the POS data, Pixel Factory can complete aerial triangulation fast and with high precision, also, the num- ber of ground control points can be reduced abundantly. But, at present, the aerial triangulation results of frame images based on Pixel Factory cannot be used for stereomapping and DLG production directly. In this paper, the aerial digital ima- ges with GPS/IMU are dealt by Pixel Faetory, then the application method of aerial triangulation results in the production of DLG is provided, and the actual data are used to test. The test results show that the method provided in this paper is feasible and practical.
