Zusammenfassung: | The invention relates to a satellite image three-dimensional area network adjustment method based on satellite-borne laser height measurement data. The method comprises the following steps: respectively acquiring first control data and second control data corresponding to a connection point from a first control data source and a second control source; carrying out combined three-dimensional adjustment treatment for the first control data and second control data on the basis of a remote-sensing three-dimensional imaging model, acquiring a parameter correction value of the remote-sensing three-dimensional imaging model, wherein acquiring the first control data and the second control data includes acquiring a plane coordinate of the satellite-borne laser height measurement data; mapping the plane coordinate of the satellite-borne laser height measurement data to a satellite remote-sensing digital orthographic image, and acquiring a footprint image; forming second control data by the satellite-borne laser height measurement data and the footprint image or partial plane control data of the footprint image; acquiring homonymy points of a given quantity in the range of the footprint image or part of the footprint image as connection points, and using the control data of the homonymy points as first control data. |
