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.
