Does the M3E RTK supports the flight mode : "smart obliques" ?

M3E normal should also have Smart Oblique Capture mode IMHO

Hi, there. Sorry for the late reply.
It is recommended that you choose "oblique" for route planning.
Thank you for your support.

Hi, there. Sorry for the late reply.
It is recommended that you choose "3D Photogrammetry " for route planning.
Thank you for your support.

Could you explain a little bit more what is the "3D photogrammetry" flight mode?
Does it take several angle pictures (like smart obliques does) ?

thanks

Sorry for the misunderstanding, please select oblique like the below photo:

thanks,
It is the same obliques mode like P4P RTK?
I mean, the drone is only able to take 1 side obliques in the same route , right?

Thanks for the information, using this route mode, 5 routes will be generated.
Route 1 is to take orthophotos, and routes 2/3/4/5 are to take oblique photos from different angles.
When uploading a task, you can choose a single route to upload, or you can choose Multiple or even 5 routes. Please note that when executed, are single by one

But this does not answer the question:
Will the Mavic 3 E be able to do SOC (smart oblique capture) as the P1? i.e. in sequence taking 1 nadir, 1 forward oblique, 1 left oblique, 1 right oblique and then 1 back oblique, very efficient to collect data for 3D city building....

Hello DJI Natalia,

sorry to hear this! I would strongly recommend that you implement the SOC capability for M3E as this would  greatly augment its usability in 3D city reconstruction....

Hi Paul,

I’m trying to understand what is the difference between smart oblique and Oblique mission. Oblique seems to be the 5 routes mission dedicated to create a 3d model of an area… now that they have included the smart oblique function under the Mapping task, I don’t understand what it would be the advantage. Time wise it seems to take more…

I have just tried SOC under mapping and IMHO it should be more efficient than oblique as it produces 2 perpendicular S flight plans while Oblique produces 5 plans (one for each direction).

Hello Natalia,

SOC is now implemented on M3E with latest firmware, Thank you!  However to augment efficiency I would suggest to take ortho or nadir pictures in both perpendicular S flight plans. This way we could reduce the side overlap to something like 40% instead of standard 60 as the plans will have nadir photos... Please forward to development team

which camera angle and overlap do you use with SOC?

May we confirm what DJI product are you currently using?
Then we can confirm this problem better.
Thank you in advance.

Hello again,
as I said having nadirs also in 2nd perpendicular plan would let us reduce side overlap and thus increase productivity.
In following image you see a SOC with 2 perpendicular plans (plan 1 with red lines and plan 2 with blue lines). As you can see only plan 1 has nadir photos.

Hi all

I'm just picking up on this - there seems to be conflicting information that M3E will do Smart Oblique with 'new firmware' or, that it won't.
I have the latest firmware on mine, and I can't see it as an option. Unless anyone knows different, or am I missing something?

Thanks
Robbie

Yes it will do Smart Oblique but DJI has it sort of hidden in Pilot 2. You have to choose to make a normal mapping mission (Nadirs only) then while on the mission planning screen there is a check box option to enable Smart Oblique there. I never use regular oblique mode now, Smart Oblique is so much more time efficient.

Many thanks for that and sorry for the late reply. Well, I did a Smart Oblique today and - I was impressed by the speed of capture, but - I don't think the model is going to work out so well. As you can see, a lot of phantom sections in the landscape, floating in space. Probably editable out in the main, but a pain.

It looks like a few of the photos just aligned at the wrong camera pitch. Did you use RTK or did you PPK your image set? With Metashape, doing so would lower the tolerance on how much the photos can be adjusted during alignment. I'm guessing you're using Reality Capture here? I'm not real familiar with that software. If you can send me the dataset I can run it through Metashape and see how it comes out there. Instead of removing the bad points, remove the bad images that are causing these points. It should be simple to spot which photos were aligned at the wrong angle. It appears to be only 5-6 problem photos.

Yes, it's Reality Capture and it's RTK, not PPK.

The image set is here: https://drive.google.com/drive/folders/1Er-HtUw6JLvZgO0WLLMnXujWCDaROhLL?usp=sharing

It's a set of about 1800 images, so I thin that it;s more than 5-6 that are out of alignment here. One thing I did notice was the drone reported 'reached end of gimbal pitch' a few times.

thanks, Robbie

Ok I got 1658 images downloaded and just started aligning it in Metashape.  We'll see how it comes out.
The "reached end of gimbal pitch" message isn't a bad thing. I believe it mainly happens while taking the backwards (past nadir) angled photos. The drone itself has to be tilted forward in order to achieve this angle photo. If the drone is not tilted forward at the time the photo is taken you'll see this sometimes. You'll also see the body of the aircraft in some photos when it's nearing the end of a flight line.

Here are the camera locations that you should be able to import into RC - https://drive.google.com/drive/folders/16WHoyT2cphB4ETFm2zoCRH7kB1mF7StQ?usp=share_link

All but 12 of the photos were properly aligned. The camera locations were also optimized with Metashape and their total error, as you can see in the screenshot, came out to 2.9 cm.

John, thanks so much for that. I rendered the model in RC and manually deleted the 'inception' parts! output to Cesium tiles as below. The result is a lot less detailed than the standard, 5-path oblique method.

Hello,

from what I can see the images Dewarp was on for first folder/plan.... If that is the case then the camera calibration should have following parameters fixed (cx,cy,k1-k4,p1,p2,b1,b2)for first folder/plan images...

One reason is that the SOC was set up with 30 degree pitch while maximum is 45... Max  would probably give better results...

Ah yes very good catch, I didn't even notice this until you pointed it out. Dewarp was on for the first flight but not during the second flight. It's much better to leave dewarping off entirely. What you defiantly don't want to do is have a mixture of both in the same dataset. Im running a new chunk on just the second flight and I bet the accuracy will go up a bit.

Yes they did.

I've never imported cameras into RC I found this forum post and went off it. Maybe it can help you on importing. It sounds like you already have the data you wanted though.

https://forums.unrealengine.com/t/import-agisoft-camera-alignment/711976

This is an excellent forum, many thanks all. Some of the RC stuff is well beyond my current limited skillset - changing camera calibration parameters and alingments, etc. Sorry to say that I am very much of the 'import, render, trim the edges export tiles and orthophoto' level at the moment though that will improve...

I will run it again when time allows and ensure to use 45 degree angle and no dewarping.

Thanks again!
