The invention provides an image matching and positioning method based on point feature and contour feature fusion. The method comprises the following steps of after Point feature detection, calculating segmentation thresholds, binarizing images, searching through contour edge points; performing contour approximate fitting to fuse point features and contour features, performing feature descriptionand feature matching, performing mapping matrix point screening, calculating a mapping matrix and a matching position, mapping a real-time graph center coordinate to a reference graph, and performingcompensation according to flight platform attitude information to obtain current geographic position information of the flight platform. Point features of the method have intrinsic contour constraints. Mismatching points can be quickly and effectively eliminated through contour features. The method has following advantages in that a mismatching problem caused by single point feature matching is avoided, matching correctness is improved, heterogeneous image matching positioning of the flight platform shooting real-time image and the satellite remote sensing image reference image is realized through point feature and contour feature fusion, and relatively high correctness is realized compared with a present matching algorithm.
