If you know in advance, the trajectory that the drone is supposed to take during its usage in production, then you should simply perform the mapping process by following the same trajectory with the drone flying slowly and looking exactly towards the directions the drone will look during its usage in production. If the drone could potentially fly at two different altitudes (e.g. 2 meters and 5 meters) then you will have to perform the mapping process twice:

• one with the drone flying along the trajectory at 2 meters.
• one with the drone flying along the trajectory at 5 meters.
