Hello,
I was wondering if anyone has any experience using the different types of image processing software.
I'm particularly interested in the creation of DEMs for terrain/surface mapping.
I've been looking at the options out there. Something I'm confused about is why Pix4uav is so expensive compared to AgiSoft Photoscan.
Pix4UAV is $21000 (15500 euro)
Agisoft Photoscan is $3499 (2600 euro)
Is it really worth the extra cost?
EDIT: Hello I should edit this now as the new Pix4DMapper is cheaper and they have montly and yearly rental options

Hello,
I bought the photogrammetry software aspect3D http://aspect3d.de last year – at about the same price of Agisoft but made in Germany (I am really happy with the colored dense point clouds it's producing). You can also generate HD videos from your 3D-models with it. So far I've only taken photos from the ground while currently learning to navigate a mini copter and hopefully be ready to buy my own copter next month.
Enrique mentioned GCP... but from where can I order Ground Control Points (weatherproof) in Europe and which number and size should they be/have if I am flying above ground at about 10 – 15 meters above an area of about 30 x 50 m? How many will I need to map 100mx100m?
Many thanks, Dani

I've been very happy with Photoscan results for 3D models but have had less luck producing orthos which retain the integrity of linear features (power lines) across multiple images. Example.png attached. Any recommendations on software that will produce a more seamless representation of these features in an ortho mosaic?

Hi, in GeoScan we develop Sputnik GIS for UAVs which is compatible with Photoscan Pro:
http://geoscan.aero/en/gis-sputnik
You can find these tools useful:
Software includes 30 days trial license. If you have any questions or feature request please feel free to post here or e-mail to info@geoscan.aero.
If you have a macbook pro or mac air laptop and you need to work on photogrammetry you could add a high end Graphics card via thunderbolt 2 with this pcie expansion:

Then, you can compare the results using this free project samples from pix4D:

Try importing the project files to 123D catch, Pix4D and Agisoft Photoscan.
From my point of view, 123D catch is better for objects and fast cloud processing. Pix4D is better for user experience and precision and measurements and ndvi data for agriculture. Photoscan is more flexible but not that precise and far more slow processing data and badly user friendly.
You can try them all for free:

PhotoScan automatically corrects for the fisheye lens on my Vision 2+.

Hello David:
Yes it Does, but there is about 6cm error, with Pix4D you get about 2cm-3cm error.
Try it with this Images captured with Go Pro on both programs:

Greetings,
If I do pre-processing on the images, would that potentially get the error down to the 2cm range? I know that Photoshop has a lens profile for the DJI Vision 2+ camera.
Thank you very much.
