The invention relates to a triangle-area-representation (TRA)-histogram-based image registration method. In the method, by using geometrical invariability under affine transformation, namely triangle-area-representation histogram statistic information, a correct matching feature point pair is effectively found from a feature matching point pair sequence with an extremely low correct rate, so the stability of a feature point matching algorithm used under the condition is greatly improved and a new way for the registration of remote sensing images is provided.
