| Abstract: | GPS and IMU technology has been progressed quite great and applied broadly,the integrated application of them supplies the possibility of direct orientation and stereo model restitution without ground control. This paper introduces GPS-supported aerial triangulation and IMU/DGPS-supported aerial triangulation,discusses several application modes of IMU/DGPS integrated system in aerial photography,emphasizes on the analysis of the accuracy of IMU/DG-PS-supported aerial triangulation with or without ground con... |
