According to the characteristics of the UAV aerial image, this study proposes a method for splicing information based on the Position and Orientation System (POS). First of all, the four corners of the image are calculated according to the POS parameter. Meanwhile, the SURF features of adjacent image overlap regions are extracted. The geographic coordinates of the back image are corrected according to the position relation of feature points. Then, they are stitched according to the geographic coordinates, and the image is fused by using the progressive fading out adaptive weighting strategy. Finally, a panoramic image with good visual effect is obtained.
