Thanks to the obstacle avoidance systems on camera drone,it expands creative possibilities and enhances safety for our pilots.
The Phantom 4 possesses a groundbreaking obstacle avoidance system which makes it stand out against its predecessors.
The Phantom 4 Obstacle Avoidance features a forward-facing vision detection system to sense and avoid obstacles that are about 3′ or larger. Two small forward facing cameras give it its own pair of eyes and an ability to not only see but react to its environment. In normal flight modes if it sees an obstacle coming close it will stop and hold position, and in other modes it will attempt to climb higher to avoid the obstacle.
When testing this out, I couldn’t make the drone hit a lamppost, a tree, or me. I ran the drone right at myself three times (sorry, mom) and, thankfully, it wouldn’t come within about 2 meters (6.5 feet) of me. The drone also won’t let you crash it into the ground—its cameras on the bottom help it know how far it is from the ground, and it’ll automatically cut its speed if it thinks it’s approaching the floor too quickly.
Very brilliant right?However, fly backward or sideways toward a building, tree, car or person and you are on your own to stop a crash.Compared to the Phantom 4,the Phantom 4 Pro has a five direction obstacle sensor system and a four direction obstacle avoidance system.
The Phantom 4 Pro has both front and rear visual sensors that can detect obstacles up to 98 feet or 30 meters away. Sensors on its belly can help avoid landing on uneven ground or water, while infrared sensing systems on both sides allows the drone to figure out where it is within a space, recognizing obstacles up to 23 feet or 7 meters away. The top of the drone is the only side left unprotected.
We saw the Phantom 4 Pro take a spin around a warehouse in East London — a room full of obstacles hanging from the ceiling — and it managed to live to tell the tale. That’s encouraging if you’ve ever lost a drone in a tree.
DJI added a couple new flight modes made possible by the obstacle avoidance. One increases the system’s accuracy so it can fly through narrow environments such as through doorways or windows. ActiveTrack, the Phantom 4 Pro’s subject tracking mode, can now handle following a subject’s profile by flying sideways or backward in Spotlight mode. And its TapFly mode, which lets you tap a location on screen to automatically fly to, will now work backward and you can rotate the drone or tilt the camera without changing its path.
The Phantom 4 Pro also has an enhanced Return-to-Home mode that will guide it home from up to 984 feet away (300 meters) and avoid obstacles along the way. Also, DJI says within a minute of the Pro losing its GPS signal, it will automatically return to the last connected position and hover as it waits for your next command.
I have to say that I’m really impressed with Phantom 4 Pro and I’m sure it will not kill you.
