How Can I Upload My Flights From Litchi to Dji Go
Flight a drone manually is fun, merely there are some manoeuvres that are virtually impossible to fly smoothly. Circling an object or person, for example. You'd demand to constantly change the remainder of forward/backward and left/right inputs to fly the circle in the showtime place, then simultaneously keep rotating the camera by just the right corporeality to proceed it pointed at the centre of the circle. Anyone who can do that perfectly is either a drone genius or has way more than the usual number of hands.
The DJI Get app offers a range of intelligent flight modes – aka democratic flying. But a third-party app, Litchi, goes even further: information technology allows you to program your flight path in Google Earth earlier y'all even get out domicile. As soon as you arrive on site, merely load the pre-programmed flying and striking Outset.
I decided to give it a go with my ultraportable drone, the DJI Mavic Pro I reviewed last calendar month …
The Litchi app offers five autonomous flying modes, iv of which are aimed at video, so let's start with a quick summary of each.
Orbit is the showtime one y'all run into in the video below. You lot define a indicate (by default, the accept-off point), and the drone will automatically fly in a circle effectually it, keeping the camera pointed towards the centre at all times. You tin can gear up the altitude, radius, speed, direction (clockwise or anti-clockwise) and a few other variables, and the app does the rest.
Rail is likewise seen in the video. You depict a rectangle effectually a person or vehicle, and the drone will and so follow the subject around, keeping the camera pointing toward them.
Focus is similar, but this time the drone lets you fly it manually while the app keeps the photographic camera pointed at the subject area. If you leave the drone hovering, Litchi will simply turn it to go on the camera on the discipline.
Waypoint is the most sophisticated way of all. Here, yous tin program the drone to fly a complete 'mission' – flying to a serial of pre-selected points, and conveying out pre-programmed deportment at each one. For instance, y'all could tell it to fly around the irregular-shaped perimeter of your land, keeping the camera pointed at your house, starting video recording at the first point and stopping it at the last. Or you lot could instruct it to fly to say half-dozen unlike places, to point the camera at a different matter at each ane, and take a photo of each.
At that place's likewise aPano mode to automatically take panoramic photos. Finally, if you use a virtual reality headset, there's an FPV mode to provide you with a mock 3D commencement-person view.
One manner Litchi doesn't offer in the iOS version is Follow-me – which follows the GPS location of a smartphone or tablet. This doesn't demand to be the one controlling the app, you lot tin instead utilise a separate Litchi Magic Leash app and it will then follow someone else's phone. This is currently an Android-only feature, only will hopefully come up to the iOS version soon.
For an Orbit examination, I took the drone to what seemed like a tailor-fabricated location – a round covered reservoir. This is a big area of grass surrounded by copse. My first orbit was around the edge of this.
But I quickly plant that such a large radius is only really suitable for filming something large, like a castle. For people, you desire to be very much closer, and pretty depression to the ground. I then set the above Orbit profile: circling effectually myself and my partner, at altitude of xvi feet and a radius of 29 feet.
Speed is set in degrees per second, simply the app helpfully shows how long it will accept to complete a full circle at that speed, which is the far more than useful reference point. In this case, 7 degrees per second ways information technology will circle us in 45 seconds.
You also set the entry indicate to the circle (Nearest is safe, minimizing the likelihood of information technology encountering whatsoever obstacles forth the way), the heading mode (where the camera is facing, in this case toward the centre) and direction (clockwise).
In theory, you can tell the app the bailiwick top and it will automatically utilise the gimbal to angle the photographic camera downwards to film that height. For example, 3 anxiety should angle it toward the centre of people. However, this was the merely attribute that didn't seem to work well, and so I instead opted for transmission control of the gimbal. Yous'll see in the video that I have a few seconds at the start to angle the gimbal down toward us, but the app is doing everything else.
Gimbal control bated, I was incredibly impressed past the result. As I noted in the video, the centre signal of the circle was the take-off bespeak, non the bodily position in which we're continuing, but the drone behaved beautifully – it followed a perfect circle, and kept the camera position absolutely spot-on. The resulting footage is completely smooth.
I besides tested the Rail feature to run across whether it could follow Stephanie around the field. The central here is having a subject completely distinct from the foreground and groundwork. In the first try, I managed to get between Stephanie and the drone. At that signal, it locked onto me instead – non an unreasonable thing to do in the circumstances. When I got out of the manner, information technology successfully tracked her for several minutes.
I only included a brusk clip of this in the video as it wasn't a particularly interesting or challenging instance, but I take a program for that at a later date.
Rain stopped play before I could movement onto a Waypoint mission, but I have created missions which I accept stored in the app set up to try another time. Above is an extremely simple example of a mission where the drone climbs to xxx feet then flies effectually a cricket pitch, keeping the camera pointed at the pitch itself.
One very nice characteristic is that you can choose whether the drone flies exactly to each waypoint, or automatically smooths out the curves. In the cricket pitch example above, I created a total of 10 waypoints and selected the car-smoothing feature, which turned it into more than-or-less a circle.
Even meliorate, you don't fifty-fifty accept to tap on the paradigm to drib your waypoints: you can simple depict a line and Litchi will derive waypoints.
For example, you may remember the tumble-down castle tower in my first drone diary slice – its very commencement flying. I wanted to create a curt clip where the drone would curve around the open side of the tower, keeping the camera pointed into it, to create a passing look at someone within it. To practice this, I just drew a curve on my iPad screen and the app automatically created five waypoints for it.
That's for a project I have in mind, to feature in a future diary piece.
Pricing & conclusions
By iOS standards, Litchi is a pretty pricy app, costing $22.99 – especially given that some of its functionality is already available in the complimentary DJI Go app.
But Litchi goes well beyond the modes offered by Go, and indeed replicates some of those previously constitute only in much more expensive apps aimed at professional drone use. And even for the overlapping features, the ability to create missions from the comfort of your own home, salve them to your iPad and then load and run them once you lot're on site makes the app worth every penny.
If yous've already forked out a m for the drone itself, 20-three bucks more for an app that really lets you lot get the most from information technology seems similar a sound investment.
Litchi is a $22.99 purchase from iTunes.
