Python and Java API / Rotate chunk
« on: August 23, 2016, 06:00:40 PM »
Hello,
Is it possible to rotate a chunk so a chosen camera gets at 0.0 for each omega kappa phi angles? Would you provide a snippet code?

Python and Java API / Use camera orientation as default coordinate system
« on: August 23, 2016, 04:15:38 PM »
Hello,
I've got around using a camera as the origin thanks to Alexey snippets,
Now I need to set the angles for this camera as 0.0 0.0 0.0 so it becomes my referential, how do I do that?

I'll consider checking names and range later on for sure 
But why is this happening?

2016-08-19 14:36:10 T[i,3] = -origin

Python and Java API / Move origin
« on: August 19, 2016, 02:50:26 PM »
Hello,
Would you complete that snippet on how to change the origin?
I want the first camera to become the new origin
import PhotoScan
import math
doc = PhotoScan.app.document
doc.open("project.psx")
chunk = doc.chunk
camera_becoming_origin = chunk.cameras[0];
then transform ?

Hello Alexey,
Maybe you have a snipet code to place my chunk origin at a camera (with id parameter) as well ?
That would already help

Hello Alexey,
Meanwhile I've rotated and resized the box region, updated the reference and found only the xyz in X, Y, Z, Omega, Phi, Kappa, r11, r12, r13, r21, r22, r23, r31, r32, r33 have changed.
This leads me to the conclusion that the ΩΚΦ angles are truly Euler angles but then there is no reason why then they would fail to provide a good quaternion, is that a bug?

Thanks Alexey,
If you could point me to these specific functions that would be very nice of you.

Hello Alexey,
The chunk has no referential, no.
The shots are happening indoors anyway, so i guess it's the default one. By the way I can hardly see the scene origin on the UI
Could I set the scene origin to a camera origin? Or to the center of a given set of cameras locations?

General / About X Y Z Omega Kappa Phi
« on: August 18, 2016, 04:02:00 PM »
I'm trying to use the camera positions calculated by Photoscan, especially the angles.
The quaternions I'm computing from the OPK file's Euler angles appears to be garbage as they don't express the actual orientation of each cameras supposing the origin (0,0,0) is in the center of my model.
I'm using
# PhotoID, X, Y, Z, Omega, Phi, Kappa, r11, r12, r13, r21, r22, r23, r31, r32, r33
When i place these values to quaternions into a 3D coordinate systems I'm expecting to see radiant arrows in a plane, about this: http://www.featurepics.com/StockImage/20110114/arrows-pointing-to-center-stock-illustration-1756808.jpg as cameras are on a circle pointing inward to an object.
But I get all quaternions more or less around a straight -Y axis.
So, what is going on?
Is the origin waaay off? How would I move said origin?
Are these outputted values suceptible to gimbal lock and possibly actually gargabe?
