【摘要】 针对航拍图像的特点和难点,提出了一种基于局部特征的航拍图像拼接方法,以提高拼接的质量和速度。该方法利用多分辨率技术和局部特征对航拍图像序列进行配准。通过仿射变换模型将拼接问题转化为像素点空间坐标变换的过程。采用渐入渐出的图像融合算法,消除拼接痕迹,实现了色彩和亮度的平滑过渡。实验结果表明,该方法对航拍图像序列和视频图像拼接效果良好,具有较高的实用价值。更多还原

【Abstract】 This paper presents an algorithm of image mosaic based on local features to improve the effect and speed of aerial image mosaic.The method registers images according to multi-resolution analysis and local features.The problem of image mosaic is turned into the problem of the coordinate transformation between the pixels by using affine transformation.The weighted average algorithm is used to achieve smooth stitching results and eliminate intensity seam globally.Experimental results show that the proposed method is effective for the mosaic of real aerial sequences and video images.更多还原
