This paper mainly suggested two ways of matching method in spatial domain for high-resolution remote sensing images in order to obtain equalized distributing GCPs Ordinary matching method first manually acquires a few initial GCPs

then extracts GCPs with feature detection operators The final step is the template matching This paper suggested equalizing the GCPs either during the feature detecting or after the template matching At the end of the paper

experiments proved the effectiveness in accuracy improvement with the proposed methods
