Scanning best practices
How to configure the scanner to provide the best quality
The quality of the scan depends on multiple factors. The scanner provides a variety of settings to enable an optimal scan; however, even by rearranging the positions of the scene and scanner you can get better results. Always arrange the scene to have the best conditions for scan first and only then manipulate the settings of the scanner.
Closer objects have a better spatial resolution and generally less noise.
Material albedo (reflectivity)
A material with higher albedo provides a better signal-to-noise ratio.
Strong ambient light
Indoor ambient light generally does not influence the scan. However, very strong light such as direct sun might be a problem. This occurs especially when scanning outdoors. Try to remove all sun illumination e.g. by shadowing the window, or by moving into a different place.
As a rule of thumb: Take a flat piece of the material and try to look at it as it be a mirror. If you are able to recognize a shape of your head as reflected by the material, the material is glossy. Depending on the scene, some parts might be not scanned optimally.
When scanning glossy objects, find a position where light coming from the projection unit does not illuminate other objects on the scene. To further increase change of optimal scan while scanning glossy materials, use the “Scan glossy / Scan on sunlight” setting. Using this setting will increase the scanning time.
