When we plan the flight route of an oblique photography task  , in order to collect the texture information of the building at the edge of the target area, usually it is necessary to expand the flight area.
But this will result in a lot of photos that we don’t need at all, because in those extended flight areas, there’s only one of five lens data that towards the survey area is valid .
A large number of invalid photos will result in an increase in the final amount of data, which will seriously reduce the efficiency of data processing, and may also cause errors in the aerial triangulation(AT)  calculation.
The sky-filter software can effectively reduce invalid photos by 20%~40%, reducing the total number of photos by about 30% and improving the efficiency of data processing by more than 50%.
