| 摘 要： | 针对真正射影像在生产中遮蔽检测和纹理修复的问题,该文提出了一种基于面元和投影方向自适应确定检测路径的高程遮蔽检测方法用于解决真正射影像生产中遮蔽区域的检测问题;提出了一种基于影像方位和建筑物倒向判断的遮蔽补偿方式,用于解决真正射影像生产中遮挡区域的纹理修复问题。实验表明,本文方法提高了真正射影像生产的精度和效率,遮蔽检测效率较普通的高程射线追踪方法可提高一个数量级以上。

| Abstract: | According to the key technology problems of occlusion detection and texture repair,this paper proposes a new method that adaptively detecting the occluded region based on panel and projection direction,which is applied to solve the issue of occluded area detection in true orthophoto production;Besides,this strategy presents a way of compensating the image based on orientation and building backward in the texture repair of occluded area,and be used to deal with the texture repair.Finally,compared with the traditional methods,it turned out that the experiment results extremely improve the efficiency and precision in the true orthophoto production,the efficiency can be highly up to ten times more. |
