【Abstract】 The elements of exterior orientation of the aerial photos can be got directly by the aerial photogrammetry with the technology of IMU/DGPS(Inertial Measurement Unit/Differential Global Position System).It can reduce the cost, improve the efficiency of production and shorten the production period. By the relevant test and the practical project, this paper clarified the technical flow using this technique to produce digital orthographic map of 1∶50 000 scale, and the solution of the problems appeared during the process.更多还原
