High - resolution image based on the floating control point method orthorectified

The present invention discloses a high resolution remote sensing image floating control point orthorectified method, comprising the steps: step S101, the high resolution for land and sea remote sensing image based on the boundary extraction, select small targets in the water vessel as the candidate target recognition ; step S102, constructing a feature vector; step S103, the build training and test sample library; step S104, using a SVM or ANN method, based on the training and test sample database training a classifier, complete vessel identification, acquiring the image coordinates of the vessel; step S105, identification of vessels obtained by the morphological segment to get the geometric center line, and use of the track tangential direction AIS geometric centerline of the vessel is completed by matching the vessel to obtain accurate GPS location information; step S106, based on the image coordinates of the vessel, the geographic coordinates of control points configured to optimize satellite rational polynomial correction model, highly accurate orthophotos.
