    Crowd Counting ? ? ?

    Need P3P Filming Advice

    If you nail your exposure when capturing the images, post-production is not a mandatory thing, although you can always improve or apply personal touch to it. If you want to avoid it (editing), try to keep the histogram at the center, so the image will not be neither over nor under exposed. But...

    Need P3P Filming Advice

    The histogram is your best friend when it comes to exposure, specially when one can't see properly (sunlit screens). Here is a quick guide on how to deal with it: http://bit.ly/2qNafKn

    Litchi question

    I experienced the DJI warnings of magnectic interference, saying I should calibrate my compass (otherwise I couldn't even fly). Using Litchi on the very same spot, no warnings and perfect flight.

    Litchi/P4P - Guaranteed altitude at waypoint?

    I've experienced great precision for both position and altitude. Checking logs after the mission, the barometer altitude (or height to be more precise) had a very good match regarding the planned height at the waypoints. I suggest you create a small mission just to check it all, you will see...

    P3P Owner for 6 months, What is DJI Thinking?

    I'm a Shield user too, starting with Litchi, and as far as I've learned, you can cache but the tablet can't be turned off (to keep the maps cached). So, you would need to cache where you have wifi signal, then keep tablet on until the moment you fly. But the nice side of Litchi is that you can...

    B4A - Programming tool for Android now supports the DJI SDK

    Just checked your website, where B4X is said to be a new Visual Basic. I had Visual Basic experience some time ago (including MS Office versions), curious to try my hand on DJI SDK but no Android experience. Would B4A allow me to develop without the need to dig deep into Android?

    Overlay Gauges? (Real Time)

    Anyone knows a way to overlay control stick input gauges in real time, while flying? It would be usefult to me for more precise manual flight. Horizontal and Vertical speed tapes would be nice too. As far as I know, apps like Dashware work over recorded video only (at least that's what they...

    Help me calculate the height required

    Right, for such camera you could roughly use (for 16:9): Flight Height = Terrain Vert Dimension x 1.185 or Terrain Vert Dimension = Flight Height / 1.185 Terrain Horiz Dimension = Terrain Vert Dimension x 1.778

    Help me calculate the height required

    I don't own a P4P, but looking at the specs and considering a 24 mm lens (35 mm format equivalent), it should be: > 3:2 Aspect Ratio @ 500m AGL = 750 x 500 m Area > 16:9 Aspect Ratio @ 592m AGL = 888 x 500 m Area Let us know in case you test it and it is correct.

    Litchi large perfect circle

    That's a really useful relative ;) Maybe one day he could write your own personal app ;)

    Litchi large perfect circle

    I've created a simple tutorial (attached image), hope it helps. Did it on my computer, not tablet, not perfect, but it's a start. In case you succeed creating it, start on a smaller scale, just to try the concept. In case you are satisfied, go to full size. Good luck ;)

    Litchi large perfect circle

    I've created a simple circle, didn't fly test it yet. Search for Circle on FlyLitchi Hub, it can be moved to your location and resized, rotated. Looking at the map it seems kind of squashed, but maybe can create good results. If your primary goal is to compare different seasons, the circle...
