Aerial Images from Quadrocopter (Phantom 2 visio)

1.    Download imagick:

http://www.imagemagick.org/download/bin … indows.zip
Extract to folder  (e.g.) : c:\programs\imagick\

2.    In the directory with the images (.jpg) to straighten, create (and run) bat file containing:

for %%f in (*.jpg) do c:\programs\imagick\convert.exe %%f -distort barrel "0.01152 0.01061 -0.38333"   flat_%%f

3.    The correction parameters you wish to have, can be obtained in several ways..

Here: https://vimeo.com/51999287 is an example (tutorial) of a plugin for the program hugin and photographed grid array test.


4.    If you want to start to trim images in one step, then you need to add an option to the previous script:

-crop  XxY+DX+DY

e.g.:
for %%f in (*.jpg) do c:\programs\imagick\convert.exe %%f -distort barrel "0.01152 0.01061 -0.38333"  -crop 1000x1000+1692+1144  flat_%%f

(This script corrects deformations, then cut from the middle of the square 1000x1000px image size 4384x3288px.)

Re: Aerial Images from Quadrocopter (Phantom 2 visio)

Marek I have done my final year undergraduate thesis in the DSM generation from UAV Image. Have a look at http://www.slideshare.net/biplovbhandar … ar-project. I have not acquired the image myself, though. Currently, I am working as an intern in Kathmandu Living Labs and I am so excited to hear you were coming to Nepal. I look forward to meet you.

Re: Aerial Images from Quadrocopter (Phantom 2 visio)

There is an interesting discussion regarding drone mapping and some good hints in russian forum:
https://forum.openstreetmap.org/viewtop … =4428&p=11

you can use google translator for understanding the discussion.

Very good results they got with open source tools: https://pavl.uk/tiles/kislo1b/
