摘要
利用GPS/IMU辅助对超高分辨率航空影像进行加密,通过9种不同的加密方案,探讨了不同方案下的加密精度。结果表明,地面控制点、GPS/IMU观测值对辅助航空摄影加密均能起到一定的作用,对如何进行数据处理提出了相应的建议。
Using GPS/IMU-assisted to encrypt ultrahigh resolution aerial images, through 9 different encryption schemes, we explored and analyzed the accuracy of the different encryption schemes. The results show that ground control points and GPS/IMU observations can play a role to promote aerial photography encryption. Finally, we put up some recommendations for how to conduct data processing.
