DM Update: Geolocation with GPS/IMU Data and 3D STL Model Viewer w/ WebGL

http://dronemapper.com

Here is an example flight from a Pteryx UAV with 181 Images at 10 Mega Pixel. The flight elevation was around 275m average. The GSD (Ground Sample Distance) is around 13cm. We don't have support for GCP (Ground Control Points) yet, but that is on the way and will make results very accurate. We are still calculating the accuracy of our flights but they depend on a number of things because GCP are not used. This method can only be as accurate as the GPS unit. We estimate a 3-8m accuracy for georeferencing without GCP.

The above data is viewed in QGIS using Openlayers Plugin. It will read the .tfw, you should set the projection or your overall project projection to 33N WGS84 UTM.
Low Resolution 3D Point Cloud data is viewed in MeshLab.
 

You can download the results of this flight in high resolution for evaluation here.

I also setup an automated model generation from meshlabserver with a webgl viewer. It allows a nice preview of the 3D data. Tons of other updates and improvements thanks to feedback and testing from the beta crew! Thanks,

 When you say ground control points, do you mean specifically sized printed references placed on the ground of the area you are mapping? Like calibration sheets?

  Thanks :)

Yes.. sorry for the delay in reply:)
