General / Wireless SD cards

« on: August 11, 2015, 02:15:10 PM »

Hi All,

Has anyone here had any joy downloading images from a multiple camera rig using wireless SD cards rather than USB cables? Just wondering how it copes with 20 RAWs downloading at the same time if that's even possible. ( 20 camera RIG).

Many thanks.

Face and Body Scanning / Calibrating Lenses for scan perfection

« on: November 27, 2013, 06:52:29 PM »

Hello!

I'm trying to get the very best results possible from our 86 camera setup. It's a fixed studio and the lenses are always set the same. Cameras are D600's with the kit EFS18-55mm lens that came with them.

So I've got two questions really.

Before I dismantle the studio and use Agisoft Lens to calibrate all of the cameras individually, should this get better results from Scans or is photoscans inbuilt calibration just as good anyhow? ie. does it even need doing?

and...

Do the lenses focal length have to be fixed in stone for it to work? ie. gaffa taped to a position, or are they adjustable if I take calibration for 4 or 5 different focal lengths per camera? I'm not entirely sure how flexible it is once I've calibrated a lens.

Many many thanks in advance as always!!

General / One Titan or 2xAMD 7970's ?

« on: November 05, 2013, 07:26:49 PM »

Hi All.

I currently have a Titan setup and building a new PC to try and double output. We've gone for 2 x AMD 7970s instead this time. I get the impression this may be slightly faster with open-CL ..... What do you think before I order them?

Feature Requests / Split groups by default?

« on: November 05, 2013, 03:57:46 PM »

Any chance of having an option to always split groups in camera calibration. We have an 86 camera rig and find results are better if we split any groups, but have to do this step every time.

Or if there's already a way, sorry!!

General / Titan Card.

« on: September 18, 2013, 07:06:09 PM »

Hi All,

I've built an i7 with Titan as the graphics power for mesh generation.

Point Cloud is the same speed as before which is expected as I know it doesn't use GPU.

Mesh generation is much faster than my old nVidea 560, but as far as I can tell in TechPowerUp GPU it's only using 1% of GPU and a few hundred Mb of VRAM most of the time....

Does this sound correct? When is the true grunt of the titan used? Creating depth maps etc.?

Cheers!

General / force to not group cameras?

« on: July 24, 2013, 11:33:48 PM »

Hi all.
I have a small multi camera rig and not quite getting the perfect results I was hoping for.  I'm thinking that because the software is grouping cameras with the same settings as though its one camera used multiple times that it's causing issues.  Can I force  photoscan to treat every camera as an individual?

General / Polarising filter - specular highlights

« on: March 22, 2013, 01:12:01 AM »

Hi all

I have leather items, furniture, shoes etc that have highlights that break the meshes accuracy. In the past I've used matt photographic dulling spray but in this case I can't add anything to the objects. Is it possible to use a polarising filter to reduce specular highlights or can anyone suggest other methods of reducing glare. I'm using soft boxes bouncing light away from subject and yet still they exist.
