Exploration of Optimization Scheme of Aerial Triangulation Based on GF-7 Satellite Image |
| |
| Abstract: | Through aerial triangulation experiment under different control conditions and the accuracy comparison of aerial triangulation before and after image stitching processing,we detected the inner coincidence accuracy of GF-7 satellite image,optimized the scheme of control point layout in aerial triangulation,and put forward the solution of image stitching,which could provide a reference for the popularization and application of GF-7 satellite images in the construction of geographical information resources. |
