The Nettle Magic Project uses a hidden Raspberry Pi device with an IR camera to scan and decode a deck of cards marked with invisible UV reactive ink. The scan produces a full breakdown of the deck and delivers it to the performer in nearly real-time. Cameras keep adding video features, but after testing one too many video-oriented models without a complete set of audio ports, Richard Butler just had to rant.
With the introduction of the Phantom 4 RTK , DJI has brought surveying workflows closer to real-world accuracy than ever before—unparalleled accuracy within 1/10ft . The app offers direct access to all flight features, manual, assisted and automatic, and these can be selected by tapping the icons on screen. As mentioned, the battery has a slightly larger capacity than the one that shipped with the Phantom 3, and enables 28 minutes of ‘average’ flight. Older DJI batteries are not compatible with the Phantom 4, however, which is a blow if you’ve recently invested in batteries for the 3. The physical design of the camera has been refined, and part of the 4’s bulk can be attributed to the partial integration of the gimbal into the body of the drone and the new larger battery. At 1080p the camera takes a leap from a maximum of 60fps to 120fps.
This mode is for experienced pilots allowing you to fly real steady and smooth which can be great for filming. Throughout all growing seasons, multispectral imagery can be helpful to ag professionals by providing information invisible to the human eye across the electromagnetic spectrum. Instead, I’d recommend the newly released Zenmuse X5 camera which features an MFT sensor with expanded dynamic range capabilities. Then you’ll need something like an Inspire 1 drone to attach it to. Whilst you’re flying, the DJI Go app puts the Phantom 4’s main functionality only a tap away.
I’m not sure how in-depth I need to go here, I suspect you’ve seen this drone before. The Pro is a quadcopter with a rigid design and tall landing gear. You can remove the propellers to ease transport, but there is no folding features on this one. We, otherwise, have nothing new to say about the initial Phantom 4 Pro this update.
One of the biggest areas of improvement in the DJI dji drones Pro V. 2.0, when measured against its predecessor, is the camera. DJI has updated their device to include a 1-inch sensor that takes some really stunning photos and videos. We have a lot to say about the camera, but we’ll save the bulk of it for the camera section later in this review. To take full advantage of the Phantom 4 RTK’s positioning modules, the new TimeSync system was created to continually align the flight controller, camera and RTK module. A new RTK module is integrated directly into the Phantom 4 RTK, providing real-time, centimeter-level positioning data for improved absolute accuracy on image metadata. For the Phantom 4 RTK, the amount of necessary ground control is not a function of size and altitude at all.
Due to the high resolution, the dji drones RTK can achieve a ground sample distance of 2.74cm at 100 meters of flight altitude. An uprated camera is equipped with a 1-inch 20-megapixel sensor capable of shooting 4K/60fps video, and Burst Mode stills at 14 fps. The adoption of titanium alloy and magnesium alloy construction increases the airframe’s rigidity and reduces weight, making the Phantom 4 Pro Version 2 similar in weight to the Phantom 4.
