Hello,
PRODUCT : Phantom 4 Pro V2
OPERATION WITH : Apple I Pad Mini 4
SOFTWARE : Pix4DCapture
1 -When i use FREE FLIGT mode, i can not hear shooting sound.
2 -When i need manually picture and also i can not doing this with remote control.
Could you help me please. What should i do ?
Is there a solution for that ?
Mehmet
Hi Mehmet,
1. Even if you do not hear any shooting sound, the most important thing is to look if the pictures are taken by watching on the application when flying. A little camera will pop up along your flying path for each picture taken.
2. You do not have the possibility to manually take a picture when using Pix4Dcapture and running a Free Flight mission as it has not been implemented in the application. In your case, the issue is due to the fact that the SDK that allows the communication with the drone's firmware, cannot interact with both Pix4Dcapture and DJI GO 4. I will take the opportunity to share with the developer's team your feedback so that they consider to implement a feature to take pictures manually.

Hi Gaël ,
Thank you for your clear answer. But i remember, when i were using P4P with Pix4DCapture on Free Flight mode i can take the picture while drone flying and also i can here the click sound. Sometimes operator not control the speed and drone cannot take the picture in the line and when i notice this i go back and push the button and take the picture.
On my side, i have tried today P4P V2 and i see my drone is taking picture even i flying free mode. But just i can not here the sound. (i have checked also clik sound in DJI GO, it was working i can here very well ). It was not big deal but sometimes if the drone is pas the line without the picture i can control this because of sound.
If you want me to try something for this issue i would gladly try.
Best Regards,
I have a different question, In any way is it possible to automatically give a vertical flight mode to the drone so that it flies to a specific height let say 20meters and then comes down waiting 1 min every 1 meter ??
Hi Twinkle,
The Free Flight mode is semi-automatic, meaning that the control of the drone is manual and the picture triggering is automatic up to the vertical and horizontal distance you defined in the settings.
However with the Free Flight mode nothing prevents you to go to 20m high with your drone and slowly go down manually. Pictures will be triggered automatically every x meters.
There is currently no possibility in Pix4Dcapture to fly a kind a "vertical" Grid mission automatically.
Best,
Is the synchronization necessary? Can't I just load the images form Phantom SD card?
Hi Marcin,
In any case and also with the other types of mission, you can get the images acquired straight from the SD card plugged on your drone.
The synchronization is not mandatory and is here to optimize the workflow at the end of a mission so that the user can quickly look at his pictures to see if everything went fine or to upload them on the Pix4DCloud in order to be processed directly.
You can cancel the synchronization and get the images on the SD card if it is taking too much time (for example if your number of images is big) or if your drone battery is low.
Also, in the general settings, you can deactivate the automatic download drone --> mobile device at the end of a mission if you prefer to operate this way.

I want to map the top of a cliff which is at least 500 AGL from where I can launch legally. The cliff top has no access without a lot of hassle. I can launch from a public park below the cliff, but cannot map because the PIX4D Capture App limits me to 150 meters (~500 feet) above the launch point. I want to use the app because of the ability to take pictures automatically at regular intervals to do a contour mapping run. I plan the run to be about 150-180 ft above the clifftop to get the proper results. This means from launch I will need to go about 680 ft vertically. This is legal as long as I stay close to the cliff and fly not more than 400 feet above the clifftop when over it. The real question is, How can I accomplish this with your app, as it limits me from the launch point to 150 meters? I could do the mission in the Free Flight mode, right, but is it limited to 150 meters?
Hi Peter,
You should be able to realize the mission you are describing using Pix4Dcapture and fly above 150m in a Free Flight mission.
They are two important things to check to be sure that it will work:
- Make sure that in DJI GO 4, the Set Max Flight Altitude parameter is set to a value that will not conflict with Pix4Dcapture and that for example the beginner mode is not activated.
- Using the iOS version of Pix4Dcapture, you should be able to fly up to 500m in a Free Flight mission and also on Android. However, on Android, you should tick in the general settings the option Enable advance mode to bypass the default height limit in Pix4Dcapture which as you wrote 150m.
Also, even if it seems that you looked at it, be sure that your flight will be done legally regarding the drone regulations of the country where you operate.
Let me know if it can work for you.

Hello,
I have a DJI P4P pro and a Parrot anafi. I want to use my anafi for a free flight mission during a bridge inspection. I Want to visualize intrado of bridge and my P4P pro aren't able to do this.
Do you want to improve pix4D capture for this? If yes, do you have a schedule for this?
Thanks
Best regards.
Hi Valentin,
Free Flight mode is not implemented for the Parrot Anafi yet. Currently, you won't be able to make Free Flight missions with the Parrot Anafi drone. I would suggest you follow the thread which is about a similar topic.

Hello, i'm using PH3 adv, when I use the free flight mission i don't see the map and even the shooted picture when the app is running. I use Nvidia shield with android 6. Thanks for answer. Michele
Hello Michele,
If possible, can you send screenshots of the issue experienced?
I would suggest you go through the basic checks and troubleshooting first to see if it can solve the issue.
Also, are you updated with the latest drone firmware and Pix4Dcapture versions? Do you have internet access when flying this mission?
Have you tried to use another mobile device?
About the map not being displayed, it can be related to the issue describe and solved on this thread.
Let me know,

Hello,
I have a situation where by the structure I'm planning on modelling is quite large - approx 8M across and 40M high.
It's quite detailed (it's a pagoda with statues embedded).
I had planned on using a circular flight path but there is a tree situated very close to the structure that I would only comfortably navigate manually, and so I plan to use free flight mission mode.
As I will need to be physically very close to the structure as I capture it, will this be a problem? I was planning on taking images from the ground up, then moving over slightly, capturing back down to the ground, all around the circular structure.
Will Pix4D automatically capture at points that it needs to, if I fly slowly enough?
And will it alert me to areas that it failed to capture?
Thanks.
Hello J M,
Nice projects. Just by curiosity where is this pagoda?
Using your drone, if you fly slowly enough, you should not get any troubles capturing images the way you defined it in Pix4Dcapture using the Free Flight mission.
Also, it is possible to use the drone manufacturer application and trigger images manually to complete the images already taken using Pix4Dcapture.
I can also suggest if possible to flight double grid mission using an appropriate tilting angle as it will also enable to give you 3D information about the structure.
Best,
Hi is it possible to see the angle of the gimball and the height of the drone when doing a free flight mission.
Hello Jure,
As you can see on the image of the step 11, the altitude (flight height) is displayed when flying a Free Flight mission.
However, the angle of the gimbal is not displayed but you have the ability to set the tilting angle manually in the camera view so that the camera can point properly on your Region Of Interest.
Best.
Hi !!!
1] I want to map old mountain in 3d.
It is about 100 M height .
i want to capture one side of the mountain containing some structure on it.
length is about 500-800M
2] In Free Flight mission images are automatically taken by the software ?
Kindly suggest.
Hi Mahesh,
The Free Flight mode is manual, you have to manually control the drone to capture the images. I would recommend you to do the double grid mission for your purpose and see if that meets your expectation.
Regards,
Step 2-4 Set the drone into manual mode by switching the corresponding button on the controller.
I could not find a manual mode button on my DJI smart controller. Am I missing something, or is Free Flight not compatible with the DJI smart controller?
Hi Mike,
The article is referring to different flight modes. Select the mode which allows manual flying. For more information about supported drones and controller, I would suggest you go through our support article on Supported drones, cameras, and controllers.
Bonjour, j'aurai 02 questions très IMPORTANTES et URGENTES pour la mission de cartographie que je veux réaliser en mode vol libre :
1 - En mode free flight, est ce qu'il y'a recouvrement entre les photos si la distance horizontale ou verticale est fixée à 20m (distance max sur l'application Pix4D Capture) ?
2 - Si OUI, peut t-on savoir le pourcentage de recouvrement entre les photos ?
3- Si NON, quel est l'intervalle de distance horizontale ou verticale minime pour avoir un recouvrement entre les photos ?
Cordialement, bonne réception.
Hello, I will have 02 very IMPORTANT and URGENT questions for the mapping mission I want to do in free flight mode:
1 - In free flight mode, is there an overlap between the photos if the horizontal or vertical distance is set to 20m (max distance on the Pix4D Capture application)?
2 - If YES, can we know the percentage of overlap between photos?
3- If NO, what is the minimum horizontal or vertical distance interval to have an overlap between photos?
Sincerely, good reception.
Hello,
During the free flight mode, no calculation of the overlap is done by the app. If not you can use the single or double grid mission which will do that overlap calculation base on your camera parameter and the flight height.
As a general rule, if you want more overlap, fly higher and use a smaller values for horizontal and vertical distance.
