陡坡区域正射影像拉丝问题自动修补算法研究

A Method of Repairing the Brushed Problem of DOM in Mountain Area

利用航空摄影方式制作山区正射影像时,山坡区域容易在正射影像上形成拉丝现象。根据拉丝区域的形成机制设计了一种自动检测和修补拉丝区域的算法,在减少工作量的同时,也大大提高了山区正射影像制作的真实性与产品质量。

Brushed area of orthophoto is a common problem in the production of DOM （Digital Ortho Map）. In this paper, we proposed an algorithm to detect and repair the brushed area automatically. It can greatly reduce the workload and improve the authenticity of mountain orthophoto production.
