| 摘 要： | 经过正射纠正后的真正射影像,往往会出现建筑物遮挡造成的影像信息缺失区域。本文采用相邻影像补偿、图像修复两种方法依次对这些缺失区域进行补偿。对于因相邻影像信息不足,仍未补偿的剩余像素,在引入DBM模型的基础上,进一步提出一种基于有效像素的样本纹理合成方法,实验结果证明,该方法优于常规图像修复算法,生成了完整的真正射影像。

| Abstract: | There are always occluded areas on the rectified true orthophoto,which are caused by the buildings.This paper includes two steps to fill upthe occlusions.They are compensated by neighboring images first,and then by the image inpainting.As a result of deficiency of information,it remains a quantity of pixels which are not compensated by neighboring images.On the basis of introducing DBM,a valid-pixel-based inpainting method is proposed to fill upthe remnant pixels.It is verified by the experimental results t... |
