Before Scanning
4.1.
Object
EXScan S can scan objects from 30*30*30mm ^3 to 200*200*200mm ^3 with turntable or scan
objects from 30*30*30mm ^3 to 700*700*700mm ^3 without turntable.
We do not recommend scanning:
moving or vibrating objects, which cause the shape of object changed during scanning process.
Soft material object
lattice structures with many small deep holes
During scanning the shape of the object needs to be maintained without any changes (human bodies
must be held still, for example).
Example of object that is difficult to scan
4.2.
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).
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.
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.
The can is symmetrical
and has no geometry
features on the surface.
It is difficult for the
software to align the
scanned data.
