Had a Bug in my Panohead, need XML file for 1116 pics...

by vklaffehn » Tue Sep 06, 2011 10:32 pm

Hi!!

Back from Norway!!
I shot a hires pano with my selfmade MiniPanoBot and a Canon Powershot SX10is and discovered a firmware bug, a rounding issue. Now I have a 31x36 image set taken the GigaPan style, 36 images per column from top to bottom and 31 colums. The Camera was rotated 2° on the y axis and 3° on the x axis. But due to my bug, each colum starts lower than the one before, so the images that should be next to each other are shifted down, i.e. the middle image in the first column is centered at the horizon, in the next column, its shifted down, and in the next itsshifted down again down and so forth.... see image.
The gigapan importer shifts the images if there are enough control points, but not everytime, and of course not on water and sky pictures. So I thought of generating a XML file with positions, but for 1116 images i wont do that with notepad, so is there an easy way to generate such a file? If not, I'll write a small tool wich will do it, but maybe I can use PapyWizard for that? thanks for reading !!!

the other image is he glacier in low resolution, just for your vieweing pleasure ;-)

Did you try using Papywizard in simulation mode to create an XML file?

I've installed Papywizard but cant figure out how to replicate my setup, especcially the image shift with it.... My Panohead works a bit different in setup, you set an image width in °, an image height in ° and the x and y steps in °, center the camera on the middle of the scene, and then it starts at - width/2 and -height/2 and stops at width/2 and height/2.

in this case it was set to 90°70, x-step 3° and y-step 2° , (hmmmm, gives 93°x72° ...)

You cannot emulate the image shift but (I think) it's worth trying it anyway.

Because you must produce a matrix of 31x36 image shooting positions the only parameter you can readily manipulate in this situation is the amount of overlap - and in papywizard that's a single value for both axes.

So ...

1. Set the Hardware/Plugins to simulation - screenshot 1.

2. Set the Configuration/Ca,era/olesn parameters to match your setup - screenshot 2.

3. Set the Configuration/Mosaic parameters to match your shooting pattern - screenshot 3.

4. Make the connection (Hardware/connect) then define the matrix by entering the correct values for Nb picts - screenshot 4.

5. Perform the simulated shoot to create the XML file - screenshot 5.

Hi!
I now have tried the import with a simulated Papywizard XML file, see the results :
the image shift seems to much, although I get a better result than with the gigapan importer.

Sure, the actual version can be seen here (only in german at the moment) : http://www.roboternetz.de/community/threads/42241-MiniPanoBot-V.2-Panoramafotografieroboter?p=468240&viewfull=1#post468240 I'm building another one at the moment, with stronger gear and Bluetooth control interface, but it's far from finished yet ... The Idea was a small machine with the possibility to set it up without smartphone/computer

Try reducing the % overlap.

As far as I can see in the Papywizard settings, it's set to 11% at the moment, and I can't go below 10%. I've tried to edit the data in Excel 2003 to add my Offset per column, import is fine, but I cant export. So it looks like that I have to hack together a small program wich generates a XML file the way I need, should not be that hard ...

Nice!

Are the parts laser cut?

Thanks!

No, they are done on my own small CNC mill, see here : http://www.youtube.com/watch?v=8Jr7Bk0Ki-k
