IKONOSRPC data update method using a small number of ground control points

摘要

More precise topology information can be extracted from satellite images by improving the accuracy of RPC parameter data for a RFM sensor model by using only a small number of GCPs. That is, the number of GCPs required for extracting the topology information can be reduced by generating pseudo GCPs from the RPC data or composing a parameter observation equation by using the RPC data. Therefore, costs and time for actually measuring GCPs can be saved. Furthermore, since the present invention utilizes the RFM sensor model using RPC files, a new sensor model need not be required.
