The embodiment of the invention discloses an image keyword and feature point mapping matching processing method. The image keyword and feature point mapping matching processing method comprises the steps that feature points of images to be matched are extracted, and invariants of the feature points are obtained; salient regions of the images to be matched are extracted, and matching pairs between the salient regions of the images to be matched are obtained; corresponding mapping information is built according to the invariants of the feature points, keywords and the feature points with the invariants, and matching pairs between the feature points of the matching pairs between the salient regions are obtained to serve as matching pairs between the feature points of the images to be matched. Therefore, a user can rapidly and accurately find the related images through searching operations according to the submitted search keywords. According to the image keyword and feature point mapping matching processing method, the spatial constraint relation between the feature points is sufficiently used, in other words, the salient regions where the feature points are located are sufficiently used, the mismatching rate of the matching pairs between the feature points can be reduced, and accuracy of obtaining the matching pairs between the feature points is improved.
