摘要
It is an efficient way of directly measured exterior orientations using integrated GPS/IMU system. The experiment has shown that the accuracy performance of direct orientation measurement is sufficient to make orthophoto and small or medium scale map. Unfortunately, since the GPS/IMU orientation module is physically separated from the camera to be oriented translational offsets and rotations are existent and have to be considered. This paper firstly discusses the integrated GPS/IMU system and the elements of GPS/IMU-based photogrammetry. Finally, the overall system calibration is investigated through the data obtained from Jiuquan city, Gansu Province.
