Abstract

Aiming at the problem of low accuracy of the target for one UAV(Unmanned Aerial Vehicle), according to the UAV’s characteristics of UAV aerial images, POS dates and satellite digital map, a UAV image matching and targeting method is presented based on POS. At first, using the Gaussian pyramid optical flow method, the UAV aerials or video frames are real-time stitched. Then, taking advantage of POS date, the approximate area of the entire aerials or video frames on the satellite digital map are determined based on the formulated search strategy. Finally, making use of the improved SIFT algorithm, the aerial photos(video frames) and satellite digital map in this range are matched to complete the targeting. The results proved that this method can achieve a wide range of real-time two-dimensional positioning without ground control points, while the precision and speed has large improvement, which is an effective method for target location utilizing image matching.
