Another aerial photo to 3d landscape test

So here are some of the of the new 3d landscapes I have generated recently with my drone.  I’m still working out a few bugs and how to better capture data and am in contact with the companies that make the software.  One issue is water because its moving or has a nice reflections built in.  So you can see with my tests of a secret beach here in Tahoe some of the water is gone or the 3d model is deformed.

Secret Beach generated with Pix4D from about 300 images.

Secret Beach generated with Photoscan with the same image set.

You can notice between the 2 software packages that in this case with the water that Pix4D did a better job and some parts are missing in the Photoscan version.  I will try to do a recalculation of this data set again to make sure im getting the same results.

You can defiantly see the potential complexity of having the software try to build a 3d mesh with this type of data.

Here is another aerial shot right above the boat house that I posted on Facebook that got quite a few likes!

Anyhow check out all the models I have processed so far here and feel free to provide comments below.

Here is a 3d fly through I did with the Pix4d software

 

Generating 3D landscapes from Aerial Photos Part 2

After spending a bit more time testing various software to generate 3d landscapes I wanted to write up a second post with more detail and showing off another data set I collected the other day while hiking around Donner Lake area near Lake Tahoe.

First part of the post can be found here.

Let me first talk about my setup more in detail.

About a 2 1/2 years ago I started playing around with drones from the small cheap $50 ones to eventually shelling out and buying a DJI Phantom 2 which then I added on various components.

Here is a shot of both of my birds before doing a shoot at Emerald Bay in Lake Tahoe.

So as mentioned in my first post I had been trying out Pix4D application which has some nice features but its quite expensive.  I also recently ran across recently Agisoft Photoscan which has some similar features to Pix4D and is a little less expensive if you buy the standard edition.  I guess it would depend on what you want to do with each software and Ill mention the pro’s and cons later in this article but both give you a trial version which you can test out for yourself.

Generating 3D landscapes from Aerial Photos

I love playing around with new technology and my I have a strong background in 3D modeling since I was a young kid and got a job in the video game industry.  I’m also always looking for new ways to use my skills test out new ideas.

I have been playing around with the idea of using my drones to build 3d landscapes and over the time tested various software to help convert 3d aerial photos into 3d objects.  Granted some of my first tests didn’t turn out as well as I thought so I kept playing around to see what I could come up with.

I’m using Pix4d to convert the Nadar type of photos (basically the camera on the drone looks directly down at the ground).  I use my iPad Ground Station from DJI to fly a grid style pattern making sure I have enough overlap of images taking fro the GoPro.
