提出了一种针对低能见度、前下视航拍机场图像中自动检测机场跑道的方法。

To solve the problem of detecting the airfield runways automatically in forward looking aerial images with low visibility, a method was proposed.

youdao

前向散射能见度仪测量前向散射光强度，确定大气的消光系数，进而获得大气的能见度值。

The intensity of forward-scattered light is measured by the forward-scattering visibility sensor, which determines the extinction coefficient of the air, then the visibility can be obtained.
