General / Turntable troubles
« on: July 10, 2016, 06:26:24 AM »
Hi Agisoft Community,
I'm hoping you may be able to assist me. I've been able to get some rough models generated when I walked around the subject but because the project I'm developing demands higher quality models to be imported into VR headsets I decided to invest in a photography turntable, however the results have been less than stellar. At first a lot of my photos looked as if they were all coming from a single point and not as if the camera rotated around the subject (like a turntable is supposed to mimic). I've been working off of this tutorial:

So I used the "From Background" method of masking and Agisoft got most of the background but I had to manual go in and add the missing parts of the selection till I got something a little tighter (see images). This got my a better result (it actually looks more like the little robot I'm shooting) but it's still pretty garbled. I'm using a light tent and trying to keep the lighting as flat as possible and taking multiple shots but I'm still not getting the model to look the way I need it to look.
Am I missing something? Or is there some setting I need to put Agisoft on to process turntable photos? Is it because I'm taking too many photos (last scan of this robot was 59 photos)
I using a 16 mp Sony a55 DSLR Camera with 18-55mm lens
Light tent
Arqsping Turntable
Remote cable shutter trigger set at 1 photo/sec
Shooting all images in JPG & RAw
Once I have these models I was wondering what the best way is to get a HD model without it killing my computer. Low poly model with HD texture? I need it to be able to operate withing a VR headset which that in and of itself is a big challenge.
Any help you can provide is greatly appreciated!
