Linear feature can provide more information than point feature and can be extracted and described conveniently compared with the planar structure in the aerial images, a new straight line extraction method for steroimage feature matching is proposed, mainly for the man-made objects. The fusion and the filtering strategies are designed for the linear features extracted from the aerial images, and then feature grouping is implemented among the linear features, and each feature group contains its associated matching relationships. The experimental results show that the proposed algorithm is not only more efficient and robust but also can get richer and more accurate straight line information, especially for the buildings.
