Scanned Objects; Requirements; Sticking Markers - Shining 3D EinScan Pro 2X User Manual

5.1 Requirements

EinScan Pro 2X series can scan objects from 30*30*30mm ^3 to 4m length.
We do not recommend scanning:

moving or vibrating objects, which cause the shape of object changed during scanning process.

lattice structures with many small deep holes.
During scanning the shape of the object needs to be maintained without any changes
(People must keep still while doing human body scan, for example).
The can is symmetrical
and has no geometry
features on the surface. It
is difficult for the
software to align the
scanned data.

5.2 Sticking Markers

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 sticking markers on the scanned object surface:
(1) Stick at least 4 markers in each frame (one scanning field of view). Control the number
of markers seen on the camera view.
(2) Stick markers in a random, non-linear pattern (see image below).
(3) Markers should be stuck on the flat surface area and keep the marker surface flat.
(4) Use the markers provided with the device only. Other markers can result bad accuracy
or not to be seen.
If the object is small enough for each frame (scanning field of view), markers can be placed

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