thank you Andrew for the tip !

I don't know how exactly the masks are used by PS, however I have another practical question:

Is there any way to remove the masks ??

I need this function when I generate the masks from the model to perform alignement on model only (especially for aligning chunks). As these masks are really not perfectly fitted to the model, I would like to remove the masks to generate the point cloud. Unfortunately I did not find the function and you can not deactivate the mask in point cloud generation (maybe a feature to add in the 'Build Dense Cloud Panel'?).

Hi Stephano,

Sorry I didn't read well your first post and took the NIR for the normals of the points.
I don't work with multi-band images so I don't know/test if you can export extra value.
For sure the PLY format can handle it, but it only depends on Agisoft to allow exporting all channels.

I hope you find a solution soon

hi David,

could you please put the corresponding manfrotto reference?

You can easily export the pointcloud with the PLY export format.
Uncheck the binary option and you will have an ASCII file with the following data for each point:
x y z nx ny nz r g b

If you want to import the point cloud to a generic application as an ASCII file, just remove the PLY header.

I would recommend to use Textpad, which is well adapted for editing large ASCII files.

Buy a circular polarizer filter for your lens.  It gets rid of specular reflections.  Also shoot RAW and reduce highlights in Lightroom before processing in Photoscan.

Jeff, I understand you are using polarizer filters. I think about buying such filters, but it is quite a big budget with multiple cameras.
Could you please give us some feedback with these filters:
does it change radically the reconscructed model ?
do have noticeable improvements in hairy areas ?
do you have 1 filters on the flash units and 1 on the cams ?

Brian33433 as an example, I have just started to set up a rig with 6 fixed cam with flash synchronisation
I get nice result for the front face, but the ears and back of the jaws are clearly missing details
I have tried assembling some chunks with photos taken with my head turned side to side but the alignement between chunk was not perfect and I will have to manually remove the gap between chunks as you can see in the attachement
12 cams seems the minimum for the face including ears (only front side of the ears)
good luck with your rig

Nice rig !
On your installation mosaic picture it seems that the scanned person is laying on the floor which gives not very flatering faces with the fleshy parts moving backwards
couldn't you install it on the wall instead ?

Yes, having the image superimposed to the points when using the Look Through function would help deciding if the image should be realigned or even discarded, as you can on other photogrametry software such as photomodeler.

After trying photoscan on game card (GTX285) and pro card (quadro 4000), i would definitely go for the pro card on my next configuration.
I haven't being able to compare performances cause the CPU and memory are not the same, but my GTX cards goes up very fast to high temperature (100°C) when the GPU is 100% used, while quadro is almost no affected and remains around 60°C.
With such high temperatures, it happens very often to crash the nvidia driver and even the computer.
