UAV 3d model

Posted by Jost Laznik on December 28, 2011 at 9:49am

Yesterday we scanned an area of around 2 million square meters and made an Ortophoto model with DEM 3d output. The flight was 15 min long. As you can see from the 3d model we scanned an area with diverse terrain. What is fascinating here is that the altitude error is less than 0.5m. From these models we can calculate yearly wood volume changes, we do landslide analysis, do research for flooding areas and more unlimited options.

    As Joscht said the software he used he made himself, It would be nice if he would make it open source but that is up to him.

    What software are you using?

    As i said we test our own software. But you can do similar outputs with leica suit, photoscan, photomodeler, photosynth. But all these software is payware.

    Hi Joscht,

    Could you please let us know which software did you use to join the images and how you georeferenced them?

    If possible, could you please recommend some software that I can use to do the same as you did?

    Thanks,

    Leonardo

    Hy guys

    Thanks for your positive reaction. We (i) do remote sensing with different platforms. It really depends where is the objective located and what is the area around. (is there a good landing place...). Then i decide which one to take. I use platforms from skywalker, trainer to our custom platform as you see in my profile picture. This product i shared with you was done with low quality camera olimpus (it has some very bad diffusion at corners). I am building stabilized platform now with some high quality camera like powershot s100.  The most important steps in remote sensing are: good flight planning, high quality camera, good stabilization, high image overlap and good postprocessing. There are many programs that can provide this output.. for this particular case we used our own software that is still under testing. Visual outputs can also be done in microdem or globalmapper.  I am just computing DEM output in high resolution (just 40 hours to go :)) I am very curious what the result will be.

    Anyway i am still learning. So please share your experience so we can learn something new.

    best regards.

    Impressive. Please share how you "scanned" the area :)

    Impressive results!

    Indeed, more details would be very interesting. I'd love to reproduce around the family farm.
