23 November 2011Methods of orientating different resolution satellite images with the existing vector maps
In this paper, the different methods of orientating different resolution satellite images with the existing vector maps are
introduced. To moderate high resolution satellite image, such as SPOT5 image, the vector road maps are often used for
the orientation, and the vector lines in the maps usually represent the road central lines. And to higher resolution satellite
image, such as QuickBird image, the vector lines in the maps usually represent the road edges, instead. Beside that, the
different extend of details of the images makes it necessary to handle them with different methods. Because in very high
resolution satellite images a lot of disturbing image features will be extracted along with the wanted one. A voting
algorithm is employed to solve the problem, the approach is based on the previous work where an edge-based voting
strategy was studied. The voting algorithm has the advantages of globally optimal and robust to noise. It can directly
estimate the transformation parameters, meanwhile providing the potential matches of edge points, these matches can
then be used in calculating the accurate orientation parameters, and providing the chance of change detection since the
unchanged objects can be marked out with this method.
