Always refocus before capturing additional shots in the event that the subject has moved beyond the focus point. Refocusing is also needed when switching from close shots to long shots during recording. This DJI accessory incorporates an updated 45″ Drone Parachute system. MARS has boosted the parachute size to aid safe recovery of the Phantom 4.
You’re also likely to need a 20 minute firmware update before using your dji fly for the first time, which requires a computer and an Internet connection. To be able to pilot your Phantom 4, you need to install the DJI Go app on your mobile device. Whilst some previous iterations of the Phantom drone required the user to purchase a separate GoPro, the Phantom 4 comes with an attached camera. For those who don’t know, the zebra lines provide a live visual cue as to any area of your photo that is ‘blown out’ – i.e. retaining little to no visual data.
Much of that stability comes from the Phantom 4 expanded array of downward cameras and sonar sensors. The Phantom 4 has double the number of downward facing cameras compared to the Phantom 3. This comes in handy indoors, which is one place the Phantom 4 is nothing short of incredible.
Without up-to-date firmware, drone functionality could be limited. Compared with the Phantom 3 Pro, the Phantom 4 flies a few minutes longer , is faster (45 mph!) and weighs slightly more, so it’s a bit more stable underway. If there’s an obstacle in the way, it will fly around it – automatically. To do this, the Phantom 4 PRO uses forward-looking, rear-looking and downward-looking optical sensors to detect objects up to 50 feet in front of and 30 feet beneath the platform.
TapFly, which lets you move the Phantom to a point in space by tapping on it in the Live View feed, is joined by Draw. Draw works in a similar manner, but lets you draw a flight path on your screen. The drone will fly along the path, avoiding obstacles using its forward and rear sensors along the way. The default remote controller of the DJI dji drones RTK has a built-in screen and a replaceable battery compartment. This way, you do not need to connect your controller to the charger and wait for it to operate again. You can have a backup battery and replace the battery when it is required.
If you are on a tight budget and need an entry-level drone for smaller projects with reasonable resolution and absolute accuracy, the RTK is worth a closer look. If you are new to drones, you can do what many people do and get this entry-level solution as a proof-of-concept for basic project needs. When you need to cover more area with better-quality images, you can switch to a more expensive system. An on-board real-time kinetic sensor geotags each image as it’s captured, so when the aerial data is corrected against ground control, surveyors are able to reach centimeter-level accuracy. Not only are they reaching 1/10ft accuracy, they’re doing so every time they fly. Image quality for both stills and video is excellent, although like most drones with a 1-inch sensor or smaller, the best results are achieved at lower ISO settings.
