method and recorded media for sensor modeling of satellite imagery

摘要

PURPOSE: A sensor modeling method for satellite images is provided to model even a satellite image obtained when linear CCD arrangement is changed and to improve accuracy of satellite image. CONSTITUTION: A nonlinear sensor model that simplifies coordinate values using ground reference point coordinates and image coordinates of a satellite image obtained through pushbroom method using a linear CCD into linear values is united with a two-dimensional image conversion function, to acquire coordinates of an object to be photographed(S3). Accordingly, even a linear CCD satellite image that does not maintain the original image state is modeled.
