Riding the wind, skyrocketing, overlooking the world is the dream of many people since childhood. The rapid development of commercial drones has made this dream a reality. Relying on drones, we can watch the living city from a whole new perspective and savor the natural scenery from different heights.

However, "drone" is still operated by humans after all, and accidental mistakes, unforeseen natural conditions, etc., will have adverse effects on flight. When we are immersed in the pleasure brought by the drone, we suddenly find that it has collided, and our hearts can't help but "horse" galloping.

How can this situation be avoided? Can't afford to provoke, to avoid. Hit the eye for the drone and teach it to actively avoid it! As the saying goes: Know yourself and the enemy, and you will be victorious in a hundred battles. Only when obstacles are detected in advance, a path to avoid can be planned.
