5. Before Scanning

5.1. Object

During scanning the shape of the object needs to be maintained without any changes.
The can is symmetrical
and has no geometry
features on the
surface. It is difficult for
the software to align
the scanned data.
Before scanning black, transparent or reflective objects, spray them with powder.

5.2. Preparation

To align data if geometry features are not sufficient, you need to stick markers or pieces of clay
on the surface of scanned objects to create extra "features".
When you stick markers on the surface of the object, you need to follow the following rules:

Make sure sticking at least 4 markers in each frame (one scanning field of view). Control the
number of markers seen on the camera view.

Stick markers in a random, non-linear pattern (see example below). Four markers are required
for public area alignment.

Markers should be stuck on the flat surface area and keep the marker surface flat.

Use the markers provided with the device only. Other markers can result bad accuracy or not to
be seen.

Example of object that is difficult to scan
The pure black letters are hard
to be seen by the scanner.
The silver bottom is highly
reflective, so it also hard to be
seen by the scanner.
