Hi All,<br>
<br>
On Smathermather's Weblog there is an example shown of a mesh output and<br>
orthophoto using the sensefly swinglet cam to collect the imagery. Does<br>
anyone have the step by step to get the orthophoto? I was able to return<br>
a textured mesh but it eventually errored out with "error 256" That is<br>
related to the gcp file but i was under the impression if xy data was in<br>
the header file it would use that. Any help/direction would be<br>
appreciated! My imagery was collected using swinglet cam as well.<br>
<br>
Thanks and awesome product!!<br>
<br>
Chris<br>

Ah, yes I see what you mean. Photoscan, as far as I know, only does this<br>
because you have a 3D model that you can orient and basically declare your<br>
Z axis, which is a clever approach. That means that Photoscan actually<br>
gives you an orthophoto.<br>
<br>
Hugin is just stitching and blending, as I understand it. I know Alex<br>
Mandel and Michelle Tobias have a lot of experience with Hugin... . No<br>
point in ODM recreating that functionality, I think (though willing to be<br>
proven wrong) although plenty of reason to integrate that wonderful<br>
multiscalar blending algorithm... .<br>
<br>

Check out the runtime parameters here:<br>
<br>
<a href="https://github.com/OpenDroneMap/OpenDroneMap/wiki/Run-Time--Parameters" target="_blank">https://github.com/OpenDroneMap/OpenDroneMap/wiki/Run-Time--Parameters</a><br>
<br>
If you scroll down you'll see a reference to --odm_georeferencing-useGcp<br>
which defaults to "true". You can see it here in the run script as well:<br>
<br>
<a href="https://github.com/OpenDroneMap/OpenDroneMap/blob/gh-pages/run.pl#L107" target="_blank">https://github.com/OpenDroneMap/OpenDroneMap/blob/gh-pages/run.pl#L107</a><br>
<br>
Looking at this line of code you'll see that when you set the value to<br>
"false" this line gets executed:<br>
<br>
<a href="https://github.com/OpenDroneMap/OpenDroneMap/blob/gh-pages/run.pl#L781" target="_blank">https://github.com/OpenDroneMap/OpenDroneMap/blob/gh-pages/run.pl#L781</a><br>
<br>
That should extract the GPS info from your images and place them<br>
in odm_georeferencing/coordFile.txt. So my suggestion would be to run your<br>
project again like this:<br>
<br>
../OpenDroneMap/<a href="http://run.pl" target="_blank">run.pl</a> --odm_georeferencing-useGcp "false"<br>
<br>
That will start everything from the beginning. A better way may be to do<br>
this which should start you from the georeferencing step:<br>
<br>
../OpenDroneMap/<a href="http://run.pl" target="_blank">run.pl</a> --start-with "odm_georeferencing"<br>
--odm_georeferencing-useGcp "false"<br>
<br>
Good luck and let us know how you get along.<br>
<br>
Dennis<br>

Hello,<br>
<br>
I have been digging on the Georef code and found this, after the Bundler<br>
file parsing, and creating a pose matrix (concatenating the Bundler's R and<br>
t matrices,<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
<br>
* pose = pose.inverse(); // Column negation pose(0,2) =<br>
-1.0*pose(0,2); pose(1,2) = -1.0*pose(1,2); pose(2,2) =<br>
-1.0*pose(2,2); pose(0,1) = -1.0*pose(0,1); pose(1,1) =<br>
-1.0*pose(1,1); pose(2,1) = -1.0*pose(2,1); if (pose_ != NULL)<br>
{ delete pose_; pose_ = NULL; } pose_ = new<br>
Eigen::Affine3f(pose); rot = transform.matrix().topLeftCorner<3,3>();<br>
// Calculate translation according to -R't and store in vector. t =<br>
-rot.transpose()*t; transform(0,3) = t(0); transform(1,3) =<br>
t(1); transform(2,3) = t(2);*<br>
<br>
Why would you estimate inverse pose, do the "column negation" and after<br>
that do the *t = -rot.transpose()*t; *(This is actually documented in the<br>
bundler file, what I dont' understand is why would you invert the original<br>
pose matrix and do the "column negation")<br>

Hey Guys:<br>
I hope you are all doing well! My name is David Li, I am computer science<br>
major from the University of Michigan. First I want to thank you all for<br>
your contribution to this project. Currently, my team and I are trying to<br>
enable a drone to fly over the crops of mid to large farm owners to<br>
accomplish crop surveillance for them. We tried the opendronemap on VM. We<br>
tried to run ODM with around 70 photos and it took more than an hour to<br>
finish. While we are impressed by the quality of the resulting picture, our<br>
sponsor has pointed out the image processing process was a little too long.<br>
We were wondering if there are ways we could reduce this time so we are<br>
closer to our sponsor's requirement. Any help would be wonderful! Thank<br>
you so much!<br>
<br>

What are your current VM specs and what is your sponsor's requirement<br>
regarding processing speed? I have a sample set of about 90 images that I<br>
use to test the latest ODM updates and it takes me a little over an hour on<br>
an 8 GB Ubuntu 64 bit VM running on Amazon.<br>
