Overlay images with swipe control

The ortho maps that WebODM creates are excellent. I also use the Mavic 3T. I’d love to be able to create a map using the RGB camera and then fly the exact same path but with the thermal camera and make an ortho with those images. Then overlay them with the swipe control down the middle and move it side to side to compare the maps.

This can be done using the DJI Flight Hub and is a pretty cool feature to have both for thermal imagery over RGB but also for comparing RBG pics to easily show progress at a construction site…

Is this not available in WebODM? Just want to make sure i’m not missing it.
Thanks
Harry

Theres a QGis plugin for that if you like to try qgis.

As mentioned above you can use the QGIS tool for this.

However, I’ve been thinking into this as well what the possibilities are for (webbased) integration into WebODM.

UAVarena
This repo has a very nice interface to compare outputs of different mappings from different applications.

Idea
What if we could use (add) this interface to compare results from different Tasks inside a Project?

So if you have a task with results

Project
|-- Task X (orthophoto, dsm, dtm)
|-- Task Y (orthophoto, dsm, dtm)
|-- Task Z (orthophoto, dsm, dtm)

One can visually compare results in WebODM with a (new) Compare Tab.
For example Task X - Ortophoto with Task Y - Orthophoto

To make it a bit more visual I tried some things in Paint

Yes, something like this would be an awesome feature! One of the main uses of mapping is to compare progress… most often at construction sites… so doing this is key!

having a 3rd app that is not web based, doesn’t really help… it needs to be integrated with this platform to provide the customer with a single source.

Dan and I were poking at updating UAVArena and then moving some of those UX improvements and tools into the WebODM viewer.

Dan is mega busy so this has been back-burnered. Do you have the bandwidth to maybe help us out?

Hi Saijin_Naib,

Thanks for your reply! I would love to contribute. For me this is new (I’m not a developer, I manage our dev projects) but I’m eager to learn. The least I can do is test functionality and give feedback.

In my team I have two senior developers who actually can do something useful :wink: so that gives some perspective.

However, for the next 1-2 months they are pretty busy with coding functionalities for our own platform but maybe this time is good to lay out a roadmap / planning and funding.

Questions

Note to self
Let me start by asking two questions in my own network:
my devs → Can we make this? And how many hours should this take?
my network → Would you like to contribute with (some) funding?

Looking forward to contribute.

Thanks!

Glad to hear there’s interest in this feature, I’ve recently started a proof of concept work in this area, there are still several quirks to fix and haven’t finished due to other commitments, but would love to fast-track this.

This will allow to compare orthophotos and other assets between tasks belonging to the same project and within the same task.

I’ve put together a fund proposal here, which people can contribute to: OpenDroneMap Funding - Quadratik

Feel free to share the link with people/companies that might be interested in sponsoring this feature?

I estimate this could get done before the end of the year with a funding push. :partying_face:

Wow fantastic Piero!

I’ll make sure I’ll forward your screen / funding proposal to my network.

Three quick questions:

  1. Does this proposal end after 12 days? I’m currently asking in my network (already 2 organisations who are very interested) but 12 days might be a bit short for the organisations to get approval. I have to make a quote and invoice for them to receive payments/funding.

  2. Is there another way to make sure the payment reaches you / WebODM? For me (my company) it would be easier to work (justify) via a quote and invoice.

  3. For me the idea of pledging funds is new. Am I correct to assume that if 4030 dollar is ‘collected’ the ‘other’ 970 dollar will be added to the the pledge (making the requested 5000 dollar?)

Thanks!

  1. Yes, although there’s some flexibility here and we could extend the deadline if it means getting this funded.
  2. I can certainly send you a formal quote; just get in touch via Contact - UAV4GEO providing company name, address, etc and pledge amount. Once the quote is approved I can just register it along with the pledges in the system.
  3. Yes. See the “How it works” page on the quadratik page for details of how exactly that’s calculated.

this solution shown here is exactly what I’m looking for and would be an awesome addition the ODM toolkit. It would make for a great tool for comparing RGB images to thermal imagery of the same area. Excellent for roof inspection and wetlands delineation.

Thanks

Community funding didn’t succeed this time, thanks to all that pledged anyway! :pray:

I went back and looked at this… is this splitter control still in the works? I contributed to the funding but it didn’t get approved. :frowning: What else needs to be done on this, this is exactly what I was looking for!

It might get done sometimes next year, but can’t promise on a timeline.
