3D scan for video concert
« on: March 18, 2014, 05:52:38 PM »
Hi,

I work for a company in Paris and I need to use Photoscan for export an animated sequence of OBJ model.

The concert was shooted by 23 camera D800 positionned in an arc around the singer.

I have synchronized all the rush in Nuke and export Tiff sequence.

Now my first question is:

Is it possible to align juste the first photo of each camera and use the resuult for all the sequence?

Thks in advance for your help,

Nico

Normally yes ... if you are absolutely sure the cameras did not move...  :)

try ALIGN one dataset

go to TOOLS/EXPORT/Export Cameras - xml format

then create new chunk, TOOLS/IMPORT/Import cameras

use on every chunk

I think it doesn't change anything... May be I miss something...

To be clear, I select the first sequence's picture of each camera, next I align photos. After that, I export my camera in Xml.

I create a new scene, import all sequence picture of each camera,( "1 multiframe chunk, 23 camera" in my case), then I import my camera in the current chunk (can't import camera in an empty chunk). The aligment begin automatically but PS don't create anything... So any idea?

Nicow : merci, je garde ?a dans un coin.
Are you retouching your scans in 3D? I mean if you are recreating a kind of "3D animation", you are looking more for the texture aspect of the scan than the accuracy of the geometry itself, right?

Just curious :)

@lecaramel: Je t'en prie ;)  tu boss sur Paris ou une boite en particulier?

And yes, we just get a 3D model animated..It's like traditionnal animation. PS make one model per frame and after that we make a sequence with the all model. It's quite dirty but the client want a destruc/destroy effect so I think it can work. But we accorded more importance to the 3D model than the texture just because the texture miss some definition and we want work on 3D deformation. Will see ;)

Non, je suis ? Bordeaux, je travaille chez Pixologic, ?diteur de ZBrush.

I'll be glad to see the result if it provide the result that your client is happy with it. Motion blur isn't an issue?

This performance?

I guess you mixed both pre computed scans sequence associated with live capture (with a Kinect style system)?

Anyway, great performance if it's what you was working on!
