Abstract

We present here a new scheme that performs geometrical correction for airborne multi-spectral scanner imagery provided that an adequate reference image, i.e., an orthophoto, is available. Instead of the ray-tracing method, we determine the corresponding ground coordinates for each pixel of an input image by integrating feature point matching under Delaunay triangulated networks. The major components of the scheme include progressive generation of registration control points, and image registration. Comprehensive investigation for quantitative error analysis is also included. Experimental results indicate that the corrected images attain an accuracy of better than 0-9 pixels.
