| 摘 要： | 针对无人机空中姿态不稳定,其拍摄影像存在倾斜、曝光不均匀等缺点,采用常规的影像匹配方法效果不佳,甚至无法匹配,而SIFT算法对图像几何变形,分辨率差异、旋转等有较好适应性.利用SIFT算法对无人机影像进行特征点的提取,并采用最小二乘算法对影像进行精匹配.同时,为了减少拼接过程中误差的传播,提出了分块拼接方法.实验结果表...

| Abstract: | The matching effect of conventional methods is poor,sometimes even not matching due to the instability of Unmanned Aerial Vehicle(UAV) air gesture and the defects such as the existence of its tilted capture images,uneven exposure.SIFT algorithm has a good adaptability for image geometric distortion,resolution differences and rotation,etc.The SIFT algorithm is introduced to extract the feature points of UAV images,and the least-squares algorithm is used to match the images precisely.Moreover,the block splici... |
