摘要：This paper presents the latest release of the system TRIADIGIT for Automatic Aerotriangulation jointly developed at the Politecnico di Milano and at the University of Parma. The system is made up of three main modules: automatic location, measurement and identification of fiducial marks (inner orientation); automatic tie point extraction; assisted ground control point measurement. Here the second module is analyzed in detail, describing the procedure for tie point selection and transfer, for improving the number of multi-ray points and for outlier rejection. Results of a series of experimental tests are reported, showing the performances of the system in dealing with block featuring different scale, image content, topography and texture
