Feature Requests / Why still no .NEF support?
« on: June 25, 2017, 01:38:53 PM »
Just wondering, is there a reason why Photoscan won't work with NEF files.  Other photogrammetry software like Reality Capture handles them without any problem.

Face and Body Scanning / Using 3D scan for augmented reality
« on: September 14, 2015, 02:44:14 PM »
Here's a quick video I put together demonstrating how to scan a person in 3D for use in augmented reality apps https://www.youtube.com/watch?v=Jgup32nHAME

Face and Body Scanning / Pls check out my animated 3D scan
« on: August 20, 2015, 04:54:52 PM »
I scanned in my female bodybuilder friend and processed it with Photoscan.  I've rigged her up as a kickboxer and put her up on my website, you can see it herehttp://www.punkoffice.com/tori
Just wanted to show peeps how 3D scanned people can be used within websites.  It should work on all browsers and modern mobile devices at 60fps.

I'm currently using diodes for the circuitry that triggers all the cameras.  This  is so the flow of electricity goes from trigger down to cameras in that direction only.  Opto-couplers also do the same thing but they are more expensive components and require power 'cos they are ICs so I'm wondering why people are using them instead of diodes?  I notice Lee Perry Smith from Infinite Realities is using them.  Are they faster than diodes?

Face and Body Scanning / Reliance on "features" are too restrictive
« on: June 15, 2015, 01:52:05 AM »
I know photogrammetry works by feature matching, which is the same as panorama.  However, I'm finding this restriction is a real burden.  Scans where a person is wearing black leather boots, or items of clothing that is a plain colour end up with too much missing topology info.  Even large areas of clear skin cause problems.  I'm wondering how other people are dealing with this problem, or are they just giving their customers a list of things they cannot wear and also patching up holes in post-production?  I'm aware that a projection system can help solve this problem but it would effectively halve the shutter speed, or worse.

I have 80 DSLRs with shutter speed 1/200 and a flash that shoots at 1/300 at full power (I can adjust that up to 1/10000 with less power).  Some cameras seem to be getting less light than others even if the cameras are centimetres apart.  Is this cos some cameras get more light from the flash than others?  If so, how do I make sure every camera gets the same amount of light?  I'm thinking I could set the flash to be much faster then fire it on front curtain for the very last camera, but how do I determine what the very last camera is?
