Title:
映像の幾何補正方法およびその装置
Document Type and Number:
Japanese Patent JP2009501996
Kind Code:
A
Abstract:
The present invention relates to a method and apparatus that obtain error correction data by adjusting the LOS vector of a sensor, and assign precise ground coordinates to respective image coordinates of an image using the error correction data and auxiliary data for the image. In the method of correcting geometry of an image using a LOS vector adjustment model of the present invention, an image, obtained by photographing a ground surface, and auxiliary data for the image, are acquired. Ground coordinates for a ground control point, and image coordinates of the image matching the ground coordinates are acquired. A LOS vector of a sensor of a photographing device is adjusted, thus obtaining error correction data. The auxiliary data and the error correction data are applied to LOS vector adjustment models, and ground coordinates are assigned to respective image coordinates of the image, thus performing exterior orientation.
