[Android] Pix4Dcapture with DJI drones

Thanks a lot for your quick reply.
What will happen if for instance the DJI GO is not forced to stop?
Will the drone crash ?
Or will it fly to another place (lost) without any control?

The common case we are familiar with is when the drone cannot connect to Pix4Dcapture if DJI GO is running in the background.
This step being required to start flying the drone, we cannot say what could happen after.
We highly recommend to make sure DJI GO is forced to stop.

If you have any doubts on the optimal workflow to follow with the app, you can refer to our getting started:

Regards,

It has been a great experience to test pix4d apk. I’ad read to many bad reviews in the Android App store, but probably they refer to old versions of the program, since this ver worked has expected.

 

One thing that I’m not able to achieve it’s to get the *.*p4d file. When mision ends and my Android tries to download the files it’s imposible to get them and *.*p4d it’s never generated. I’ve read that I still can make it work, but there is some info regarding the alttitude (ground level vs sea level) that I asume that it’s not recoverable.

 

I’ve also found some photos were the leg of my phantom 4 appears on the shot, this is happening mostly when shooting while cornering. I asume -hope- that traveling at a lower speed will reduce this effect.

 

The support team advise regarding some problems using the “view camera” option occurs on Android (Moto x play (pure on USA) Android 6.0.1). I don’t know if this is a general failure or if its a mobile device related bug. But I’m not able to see anything when the dron is on a misión and photo icons on the map won’t appear while using that feature (despite photos are actually taken).

 

All this after 3 succesfull  flights with this App. We own a Enterprise license of pix4d with a bee dron, so using this App with more cheaper drones like the phantom 4 it increases its value and appliances. Keep on the good work and I’m able to test further versions or try fixes for the problems detected so far.

Hi,
I’m running the latest beta of Pix4Dcapture (3.1.1 built 88) on Android, using a DJI P3A. Flights work flawlessly, and I really like the improvements!

However I’ve got some issues with the project planner.

I’m usually flying grid missions consisting of 1 nadir flight plus 4 oblique grids (each oblique grid rotated by 90°).

Problem 1: I create my first grid and save it. I click “add” to get the duplicated grid. Now I want to turn the duplicate by 90°. I have to do this by “swiping” the arrows, which is a bit annoying and inaccurate. Could you please consider adding a button to rotate the grid with some predefined angles such as 45° and 90°? It would make things a lot easier.

Problem 2:  Once you made a duplicate of a grid the end point indicator (the checked flag) of the older grid disappears. It happened a couple of time that I forgot which flight directions I have already programmed in, mainly because I got distracted by something. I had to go back to all older grids and double check which directions I already have. PLEASE keep the indicators in all grids and do not remove them after hitting save. In my opinion they could even be a bit larger (or add some arrows to the grid?).

A nice solution for problems 1 + 2 would be to add a special mission mode, where you only have to select the area and the camera angle for the oblique part, and the app calculates the grids automatically. I do realize that this likely requires a “pit stop function” where you can swap batteries and continue the flight.

Problem 3: So I managed to program all 5 grids in. I’m flying my first grid. The drone reaches the end point. Now it starts flying back to the take off zone. I don’t want that, I want it to directly continue with the next grid mission. Coming back is just a waste of battery life and time. The only way I managed to do start the next grid while the drone is still flying was by switching the mode on the remote from F to P, which causes the drone to stop. Then cancel the mission in the app, load the next grid, switch back to F mode, and start the mission. This works, but is not a very convenient way. Could you please add an option to link individual grid missions, so that the drone just processes them without interruption?

Pix4D added ‘Double Grid Mission’ on iOS version of Capture. Check here:

(iOS) Pix4Dcapture Release 1.3

@Alejandro

First of all thank you for your accurate review, it really helps. We’re happy that your experience with Pix4Dcapture has been great and that it worked as expected.

We tried to reproduce your issues using a Phantom 4 and a device running Android 6.0.1 (unfortunately not with your same exact device model) but our tests were successful so far. Images are downloaded as expected and the .p4d file is correctly generated. Also the camera view is working correctly, even if it requires 3-4 seconds to begin streaming the video.

What we suggest when using Pix4Dcapture is:

  • The manufacturer’s app (DJI GO) is not running in the background especially after connecting the device to the drone. (Android) Also check that this app is not selected as the default app when connecting. If needed, force the app to stop, using the application manager of the device.
  • The latest firmware is installed on the drone.
  • The latest OS version is installed on the mobile device (ideally).

Did you follow this recommendations when flying your test missions?

Lastly, please note that if you’re using a Phantom 4 or a Phantom 3 to capture your images, the geolocation of the images on the SD card should be accurate enough, so you can directly use them for processing in Pix4Dmapper, even without the .p4d that Pix4Dcapture is generating. Anyway, it is usually recommended to process the images using the .p4d file generated by the app if it is available.

Hello  there,

We are a land survey companies specialized in pipeline construction for that we need a good ground profile, the pipeline is a corridor from 36m wide and 1800km long.

The pipeline route is in the mountain and unfortunately impossible to  oriented the GRID MISSION because we are in the middle of noway see attachment.

Is it possible to import a KLM file ? of some coordinate of a poly-line (center line) 

 

@Jean-luc

We just checked your area of interest and it seems that, for that specific region, the map provider we are using for iOS version of Pix4Dcapture (MapKit) is serving more detailed imagery basemap than the one we are using in Android version (MapBox).

So if by any chance you have the possibility to try Pix4Dcapture on an iOS device, you might have a better reference to plan and orient your Grid Mission.

Here attached a screenshot of an area 3km north from TopalçavuƟ:

Unfortunately with the current version of Pix4Dcapture app it’s not possible to import KML or coordinates. For a future version of the application we are considering to add the possibility to import/save some local maps so that you can easily perform missions when the data are completely outdated/inaccurate.

Hope this helps,

Regards

hi dears. I have a phantom 3 pro and I tried to use pix4dcapture for plan a mission but I have a problem that I cannot see next button in warning window when I press start mission. lets check the steps. I used dji go for calibrate compass and checking sattelite and home point , then I closed it and opened pixed4dcapter and it forced to install ctrl+dji and run it. then planned the mission and checked sattlite number that it was 9 sattlite . pix4dcapture shows the drone,s properties like battry level and 
 . it seems all steps are true but when I press start button , a warning window appears and this window has only cancel button and I cannot see next button. the mission cannot go to next step.

please help me.

@Pahpad: I am sharing here the solution you found to solve the problem, which consisted in changing the language of the device to English :).

hola, les escribo desde Chile, primero quisiera agradecer por su constante apoyo, mi consulta es la siguiente, soy usuario permanente de la aplicación Pix4d de Captura de imágenes, y quisiera saber si es posible antes de hacer el vuelo poder ingresar un archivo kmz que sea el eje del vuelo que quiero hacer para tener de referencia del lugar que quiero capturar ya que las imágenes de base que aparecen no están muy actualizadas y por lo general pierdo tiempo en ubicar bien el área, como vuelo de mas por consiguiente tomando mas fotografías que las que realmente requiero y ademas gasto batería de mas
 espero me puedan ayudar, de antemano muchas gracias

atte.

Hola, ya salio la v.3.3.1 de Pix4DCapture, me me gustaria saber si ya se puede importar KML o coordenadas?

Hello, I came out of Pix4DCapture v.3.3.1, I wonder if I can already import KML coordinates?

 

 

Question Old:

https://community.pix4d.com/t/5250/comments/210538546

Yo tengo en Google Earth un ductos de 200km con coordenadas, a las cuales queremos monitorear con drones DJI Phantom 4.

Al ingresar a Pix4dcapture me muestra el mapa sin georeferencias/coordenads.

-Hay alguna forma de transferir de google Earth a Pix4dCapture las coordenadas?

-Hay alguna forma de ingresar las coordenadas manualmente en Pix4dCapture?

-Hay alguna otra forma de poder hacerlo, alguna sugerencia


 

saludos.

So how do we go about importing a kml/kmz into beta 3.40?

@JOSE, Mike, Julio:

With the new 3.4 version of Pix4Dcapture you can improve the accuracy of your flight planning by adding KML and KMZ layers (ground overlays, line, polygons or markers) to your project. 

On our support website you will find a step by step tutorial on how to import KML/KMZ file (from step 12 on, if you already have your KML/KMZ):

https://support.pix4d.com/hc/en-us/articles/218051003

Best regards

Unfortunately that link does not work.

 

If we are doing feature requests,


Small: Can we please be able to fly shapes other than rectangles. The ability to plan out a few grids before the flight is okay, but being able to draw a polygon around an irregular share (triangular lot, construction site w/ long driveway, irregularly shaped landfill, etc.) to get the most out of our precious 16 minutes of flight time (P3Pro). 

Large: Loading a DEM from a publicly available, low resolution dataset and doing 3D flight planning to maintain overlap going up a mountain.

General comment: Latest version (3.3.1) is very stable. The decrease in flight speed saves battery, makes the image position more accurate, and increases the total area measured per flight.    

@Mike:

I’ve updated the link with the correct url, it should be displayed correctly now. Thanks for catching that!

Se agradece la mejora de importar kml/kmz, ademĂĄs como dice Greg Hering , seria muy interesante poder volar en polĂ­gonos irregulares para sacar mejor rendimiento a las baterĂ­as, saludos desde Chile.

Hello, is Pix4D Capture Terrain aware? I mean, does Pix4D Extract some kind of altitude profile from Google maps or other Map service?.

I think that it would be helpful if one can do 2 flight plans. A first one at high altitude to extract the Terrain level from the DSM of the mapped site and a second flight plan with the corrected surface level to maintain the correct altitude in all the survey path.

Thank you very much in advance. Regards.
