| 摘 要： | 针对无人机航拍图像的特点，提出了一种基于无人机POS（Position and Orientation System）信息的拼接方法.首先根据POS参数计算出影像的四角点地理坐标，同时提取到相邻影像重叠区域的SURF特征，根据特征点的位置关系修正后面影像的地理坐标，然后按照影像地理坐标进行拼接，最后利用渐入渐出自适应权重策略对图像进行融合，得到了一副视觉效果良好的全景图像.

| Abstract: | 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. |
