app shows the stars depending on the geo position, time and the gyro angle.
skyview-we-see = f(GeoPosition, gyro, time).
I want a reverse of this.
i.e if the user takes a photo of a clear sky in night, using the stars, time and the gyro, we should be able to identify GeoPosition.
GeoPosition = f(skyView, gyro, time)
