Method and apparatus for performing geo-spatial registration of imagery

A system for performing geo-spatial registration of an input image and geodetically calibrated reference imagery comprising:

• a reference database module containing geodetically calibrated reference imagery for producing reference imagery relating to imagery in said input image, wherein said geodetically calibrated reference imagery comprises position information with respect to the Earth;
• a preprocessor for processing the input image and said reference imagery using an oriented filter;
• and
• an alignment module for aligning said preprocessed input image and said preprocessed reference imagery by performing oriented matching.

A system for performing geo-spatial registration of an input image and geodetically calibrated reference imagery comprising:

• a reference database module containing geodetically calibrated reference imagery for producing reference imagery relating to imagery in said input image;
• an alignment module for aligning said input image and said reference imagery by performing oriented matching of features in said input image and said reference imagery;
• and
• an outlier rejection module for removing inaccurate feature correlations between said preprocessed input image and said preprocessed reference image.

A system for performing geo-spatial registration of a sequence of input images and geodetically calibrated reference imagery comprising:

• a reference database module containing geodetically calibrated reference imagery for producing reference imagery relating to imagery in said input images, wherein said geodetically calibrated reference imagery comprises position information with respect to the Earth;
• an alignment module for simultaneously aligning a plurality of input images from said sequence of input images to said reference imagery by performing oriented matching;
• and
• a preprocessor module for orientation filtering said reference imagery and said input images.
