Mountain work is a test that can reflect the overall view of operating the crop spray drone . The skill of selecting control points for mountain work directly determines the level of work efficiency. Choosing a good control point can even increase the work efficiency several times, because mountain work generally requires an observation platform to guaranteed the safe work. The time to build an observation deck in a mountain is generally not less than 90 minutes, and there is no more time to build a few half days, so it is important to observe the terrain in advance.
Mountain operations fly from high to low, so operations can easily cause bombing. The reason is that the agricultural spray drone and the crop are integrated from high to low, and the height difference between the drone and the crop cannot be observed. From low to high, the sky is the background to clearly distinguish the difference between the agriculture spray drone and the crop height distance.
