Face and Body Scanning / Center Capture in 0.0.0 position

« on: December 09, 2014, 09:49:24 PM »

Hi,
What would be the best strategy to center a capture in 0.0.0 position?

I try to use markets and assign a 0.0.0  to a marker near the center of the capture, but it still puts the capture in a random center in the 3d space (when imported to a 3d packadge)

Face and Body Scanning / Fixed lens vs Multi Focal and TIF/RAW vs JPG/compressed

« on: September 24, 2014, 01:33:25 AM »

Is there a significant increase in capture/conversion quality (that justifies buying 100+ Fixed Lens 50mm for a capture system? instead of multi focal kit lens)


and is there a significant increase in conversion quality using Raw vs compressed pictures?

Face and Body Scanning / About ultra high dense could generation

« on: September 18, 2014, 03:16:22 AM »

In average (in my case) ultra high dense cloud generation up?s production time about 3 times over and it only give us about 30% better meshes.

When to use this option in a production enviroment?

What are your best  strategies to get the best scan out of  very dark and shinny skins?

Face and Body Scanning / Re: Most predicable set for better alignments

« on: September 16, 2014, 03:53:23 AM »

Hi Guys

Thanks for all the Feedback

I am using all Nikon D3200 + 18-55mm lens (going to change this for the 50mm prime)

The images do lack sharp but are reasonable

My current pipeline is

0- shoot in Raw (NEF) high quality
0a- use camera raw to push some sharp to all images and convert to TIF

1- Inicial alignment with pair pre-select
2- create model from sparse cloud
3- mask photos against low res model
4- look for un-aligned photos
5-try to re-align those photos (individualy)
6- erase photos that cant be aligned
7- re-align (full) with mask on and pair pre-select off
8- create dense cloud (high)
9- build mesh (high)
10- if mesh lacks detail
10a - re-create masks from more acurate model
10b- re-create dense could (high)
10c- build mesh


p.s- i use markes on the floor to help with scaling

Face and Body Scanning / Most predicable set for better alignments

« on: September 03, 2014, 12:43:06 PM »

Hi guys i have a 109 camera system for body scan
And i was testing agisoft?s  software

What would be the best set for the best possible camera alignments?

1- Masks on or off?
2- with or without markers?
3- pre-selection pair enable or disable?

I have made many tests but results arent conclusive and i was trying to find a working pipeline that i could use in a production enviroment

what is your experience?
