Just so you know I have the Phantom 3 Pro with all the latest firmware for UAV, controller, and Samsung TAB S 8.4 inch (SM-T700).
I found that the sequence that you connect everything is very important. It helps to enable WIFI hotspot on my iPhone before starting the TAB S. That way it finds the connection better. Then I tried just starting the Pix 4D app but it kept crashing while it tried to load the map. So I closed Pix 4D app and opened the DJI Go app first and loaded the map. Then I opened the Pix 4D app and the map loaded fine.
Your symptoms sound like you either you came close to a power line, cell tower, or there was space weather. Did you check the current solar activity at the time? There is an app called Solar Monitor.
I have a feature request that may help a lot of other people as well. For the grid mission, can you allow the elevation of the first line and the last line to be set different and subdivide the elevation of the lines in between equally? When I have a slanted site I fly manually to the lowest area and check the elevation and then fly manually to the highest area and check the elevation. If I could enter these two elevations as the beginning and end then it could fly a slanted grid mission which would save a lot of time and problems with the multi phase, multi level, stitch-together option currently used. Then I could also capture vertical faces of buildings as well with the grid mission by setting the camera to horizontal, set the first line to the height of the top of the building facade, set the last line to about 1 meter above the ground, set the grid spacing manually to about 1cm, and then stretch the grid till I get the number of lines required to cover the facade vertically by estimating the vertical spaces. Or better yet, just create a vertical grid mission option where you can set the elevation of the top line of the mission, the elevation of the bottom line of the mission, and the vertical space between each line. On the map view it would just be a line that you drag the two ends to be parallel to a facade and a certain distance away from the facade and the front orientation indicator for the camera direction. This would be much better for capturing large historical buildings then free flight mode. Thanks.
I’m still having issues with the Capture app on my Nexus 9 tablet. The app crashes even when not connected to the Phantom. From what I can tell, the tiling feature is not working, and the app is attempting to bring in all the imagery at once. The tablet gets very hot from working so much, and not only the app freeze up, the entire tablet goes into a restart mode. If anyone has any tricks on how to overcome this problem, I’m very interested to know. My thought was to get the mission made, then turn of wi-fi before engaging in the grid mission, but I cannot even get to that point.
I had the same issue. So I opened DJI GO app first and loaded a map and then opened Pix4d app and then it loaded the map fine. Yesterday I tried it agai but was not able to connect to the drone with Pix4d after connecting to the drone with DJI GO app even after closing the app. Hope the update fixes the conflicting conection between the drone and the controller. I have the P3P with Tab S. The app has to connect to the drone through the controller but the map loads from my iPhone to my Tab S over WIFI. must be difficult to wright code for this connection type.
I finally got it all to work on the Inspire 1 with Galaxy S tablet running Capture app latest version and firmware 1.04.0010. I had to un-install both DJI GO and Capture App. After Installing just Capture App it all worked.
There was one thing that does not look right. After completing the mission, the I1 immediately went into auto-land. Should it not come home first? Is there somewhere I have to set this up?
I know you are wrapping up your latest version which I am super excited for. In relation to the multi-mission grid. Sometimes I see a picture that is missed, it would be nice when you implement the multimission grid that you have the option of flying a “clean-up” mission that will take pictures that were missed. So if the app sees a gap, it fills the void.
Random feature request unless I missed something, flew my first mission today with the Capture app 2.0.4 and the Inspire 1 on a Galaxy Tab S2 8" and it all seemed to go perfectly, now this is totally my fauly but surely there is a way to detect this. I had flown the whole mission without and SD card in the inspire as it was still stuck in my card reader from the last mission/flight I had done. I know this is totally pilot error but I just wondered if this is something that can be detected as the DJI GO app warns if no SD card is detected, it would be nice if the Capture app could detect this and either just present a warning to the pilot or even as one of the check points to start a mission.
Hi Andy, I had seen a similar issue and it may or may not be the first image. Typically it has been, but I don’t think its a guarantee. It is just the first image reference in the project file. Also one thing to note, it is suggested for the time being to not use the project files generated by the capture app.
I’m confused about how to produce the most accurate results.
The documentation states that using the DJI Go app does not produce accurate geotags, and that we should use the Pix4d Capture app for higher accuracy, is that still the case?
2. If I use the photos from the Pix4d Capture app, but not use the p4d project file, do I still benefit from the higher accuracy geotags?
Firstly, thank you for a great app. It works, not exactly like one would hope, but then it is in Beta
We have a P3P running with Galaxy Tab 4 7"
I did the first successful field testing with this app today, and everything worked. Did not go 100% smooth, but it worked. Some of the problems I experienced is things that I see has already been reported, so not going to make a long thing of this. There is a few important points I do want to reiterate which is holding us back being able to deploy this in the field.
Cached maps are essential. We do not have internet connectivity out in the field survey areas.
The Copter would not auto start/take off
When I started the copter, it would start up but shut down again immediately. Took a while to get it fired up.
We lost signal for about 30 seconds, when this happened the copter did not take any pictures.
I think for now these are my main concerns. Probably the most important of the lot is to establish when offline maps will be available.
HI Reiner, just thought I would share my experience. So as for number 4., it appears the app itself tells the drone when to take a picture, so if you lost the signal, the drone has no way of knowing when to take a picture. I don’t think there is a way to tell the drone to take a picture every so many meters of flight as form what I know the SDK doesn’t support it, so the capture app has to do all the work. It would be great though if the app could tell the drone to go back and where it missed.
For number 2 and 3 try this, Have the controller in P mode, click start on the capture app, you will see the reminder to flip to F, at this point start the rotors and take off an hover at say 10 feet, now click next and you should see the check list. Once past the check list and you hold the take off button for 3 seconds, it should start. I know DJI is looking to remove the “must take off” safety feature, so we have to deal with this for the time being.
Pix4d Capture feedback after extended usage with phantom 3 pro
Hi!
I’ve used this app for several monthes with my phantom 3 pro to fly grid and manual missions for DEM model and orthophoto creation, over 20 successful output model created. Here is some troubles I ran into.
The way the app uploads the missions. It seems that the mission path is loaded directly to the copter and it perfectly flies until the batterty runs out or the mission path is finished even whtn the radio link fails.
The photos however are taken only if the link is up and uninterrupted. That leads to low number of pictures if there is any interference of if flying a long way away. Is there a way to make the phantom take photos aoutomatically without the active radio link?
Camera tilt control from the settings of the app works 50% of the time. Sometimes the craft will fly with a tilted camera, even though the setting is always to face down. Hard to tell when it happens. Could you check this behavior?
App stops responding (observed multiple times) when I am in camera view and and loose signal and then regain it. After that either tha app freezes or the the copter stops capturing images.
I understand what you are saying on point 4, however, I have used a mapping app that does upload the recording request data to the drone in some way, and if you lose signal, it will complete the route (taking all the pictures) before returning to home. So this can be done.
On point 2, again, the other app I used, completed the task of start up, take off and land perfectly. For the moment, I am doing it manually, but I am hoping this is something that will be rectified in future releases.
I’m using the capture app with the Inpsire. I updated the drone, the remote controller and the batteries. But the capture app always shows 0 % battery. Has somebody a solution?
I already tried to uninstall the capture app. No succes.
Just spent the afternoon trying this again with my P3P and Tab S. Still no luck. Two days ago I could not get it to work. Yesterday I flew over the site and just filmed 4K video. I pulled 2900 stills from the video and it ran for about 16 hours and then failed. I guess I should start smaller. Today I went out determined to get the grid mission working. I uninstalled DJI GO app. Then launched Pix4D Mapper. manually flew the phantom about 10 meters off the ground, put it into F mode and pressed Start. Everything worked EXCEPT the “grid is too large” warning always came up no matter how small I set the grid. And the grid was always green in the preview. So why does it keep giving the error? It prevents it from even starting a mission. So I had to try free flight which was wonky because of some wind. Now I discovered that more than half the image are useless because the camera turned horizontal. Hope they fix these issues and have a setting to keep the camera pointed down.
