Abstract

PURPOSE:To reduce calculation time with a simple constitution by obtaining reference points corredsponding to ground control points by the use of logical models, calculating the coefficients of polynomial and calculating distortion correction at a high speed by the coefficients thus obtained. CONSTITUTION:A control part 1 controls the operation of each portion and also calculates reference points which will be a substitute of GCP for calcultaion of the coefficients of polynomial according to physical models by being inputted with the anotation data and ground control point (GCP) data of the posture and altitued of the satellite being inputted from an annotation data input part 2. A distortion correction circuit 3, inputted with the coeffieients of the polynomial having been calculated in the control part 1, calculates the corrected coordinates at each point by being inputted with the image data from an image data input part 4 and outputs the same together with the image data to an image output part 5. The image output part 5 outputs the image data having been corrected according to the output coordinates having been calculated by a distortion correction calculating circuit 3.
