Preparation¶
Some preparatory work is required to scan easily and fast with good quality.
Object preparation¶
Scanning with turntable¶
Objects with a weight of less than 5 kg.
Objects with dimensions greater than 30 x 30 x 30 mm³ and less than 200 x 200 x 200 mm³.
Scanning without turntable¶
Objects with dimensions greater than 30 x 30 x 30 mm³ and less than 700 x 700 x 700 mm³.
Caution
If the size or weight of the object isn't within the suitable scanning range, please don't use the turntable.
Objects not recommended for scanning:
- Moving or vibrating objects, which cause the shape of object changed during scanning process.
- Soft material object, such as plush toys.
- Lattice structures with many small deep holes, such as Eiffel Tower souvenirs.
Objects difficult to scan:
- Transparent objects, such as glass.
- Objects with reflective surfaces, such as metal parts.
- Dark-colored objects, such as a black keyboard.
- Thin-walled objects, such as paperclips.
Solutions:
| Object | Preparation | Notes while scanning |
|---|---|---|
| Transparent, shiny, reflective surface objects | Use a washable or vanishing scanning spray | Scan as normal. |
| Thin wall objects | Place markers on and around the objects | Choose global marker in align mode. |
Markers preparation¶
If the features of the scanned object aren't rich enough, markers can be pasted on the object for scanning alignment.
| Scanning Range | Marker Size |
|---|---|
| 290—480 mm | 3 mm |
Please pay attention to the following details when pasting the markers:
- Attach the markers evenly and randomly.
- Four markers are required for the alignment at communal areas.
- Ensure that the device's camera can scan at least 4 markers within the normal scanning range.
- Please attach small markers on the edges or at small facets of the model.
- Don't attach the markers on the surface with high curvature.
- Don't use damaged or incomplete markers.
- Don't use greasy, dusty, or dirty markers.
