针对多视点航拍图像拼接,从提取特征点和图像合成两个方面探讨了提高全景图像拼接处理效果的途径,提出结合相邻关系图模型的局部图像融合算法。该算法采用双向验证策略,消除误匹配,提高拼接精度。采用结合直方图匹配的局部图像融合,实现拼接区域色彩和亮度的无缝拼接。实验结果表明,该方法可以减少计算量,对光照不均匀的场景有较好的效果。

To solve the problem in multi-view aerial image mosaic, the way to improve the effect of panoramic image stitching is presented based on features and image composition. A new method of local image fusion is proposed combining adjacent graph model. The algorithm uses two-way verification strategy to eliminate mismatching and improve the mosaic accuracy. By combining the local image fusion with histogram matching, the seamless mosaic is realized. Experimental results show that this method not only reduces the amount the computation but also has a good effect on different illumination image.
