Paper Abstract

To get precise directly measured exterior orientations are the key of integrated IMU/DGPS/Camera system photogrammetry. 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 IMU/DGPS 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 IMU/DGPS system and the elements of IMU/DGPS-based photogrammetry. Finally, the overall system calibration is investigated through the data obtained from Jiuquan city, Gansu Province.
