3D Scanning a Face

Goals

What I consider a good facial scan is:

  • You can tell who it is – enough features to distinguish between different people.
  • The nose looks right.
  • The shape of the head is correct.
  • There are no extra features added like double cheek bones.

This is just for the face, between ears, chin and forehead.

Initial findings

The Kinect V2 cannot scan closer than 50cm, so trying to get the face the cover the majority of the scan area is impossible; this also works out well because the edges of the scan area are not good to work with anyways.

The side facing towards the scanner is good, but the side of the face that is angled away from the scanner will be lower quality data, I think I will have to trim it out to get a good scan/alignment.

When scanning, quality is related to holding still and the distance of the scan. The closer you are, the more detail there will be- but the further away, the less movement will interfere with the scan.

How to get good quality alignment on faces

Get 3 good Scans: Front, left and right side at (45 degree angle).

Pick easy alignment points; Between the eyebrows, tip of the nose, under the bottom lip, check bones.
