Multiple Photos of Face result in Weird Final 3D Model
« on: September 12, 2016, 04:10:43 PM »
Hi,

I used a Microsoft Lumia 950 XL phone camera with 20mpx. In total I used 33 photos from different angles and heights to ensure enough photos from different views. Unfortunately, the result was quite disappointing since the model was quite undetailed although enough photos of the face were taken (see photo in attachement) I hope somebody can either give me tips on what to improve for next time or help me otherwise somehow.


Greetings,

Hello BloodFighter,

The surface reconstruction artifacts look like a result of alignment issues, probably due to the movements of the person being scanned.

Using PhotoScan I did this 3D model: https://sketchfab.com/models/00a8b9ff5d50427093d61345ed4d2c53

Camera: DSLR Canon EOS 760D (24mpx)
Lens: Canon 24-70mm L f4 IS USM
Lights: 4 x Hakutatz VL-9099 arranged around the model

In total 198 photos. (f22, ISO 100, shutter speed 1/60)
