EinScan H - Overview of Scan Modes

This article was created using software version

The EinScan H supports 3 scanning modes dedicated to scan objects, the human body and the human face.

This article introduces these 3 scanning modes as a handy reference guide and to help on the selection of the most suitable mode for each project:


The following table summarizes the specialisation for each mode and the differences between them:

Standard Scan

The Standard Scan mode is recommended to scan objects, from 300 mm to 4 m.

It is not advised for scanning:

  • Moving or vibrating objects
  • Soft material object
  • Lattice structure with many small deep holes

Moving or vibrating objects, as well as soft material objects, which are likely to tremble, might lead to misalignment. 

Small holes or narrow spaces or sockets might not be detected with the EinScan-H, due to its large scanning area.

The Standard Scan mode is therefore suitable for objects with good geometry or texture features. 

The usual techniques to deal with objects with black, transparent, shiny or reflective surfaces, as well as objects with less features or repetitive patterns, also apply to this scanner.

Body Scan

The Body Scan mode is recommended to scan the human body. No matter if only a part of it or the full body (except the hair).

Please keep in mind that hair cannot be scanned in this mode. Please refer to Face Scan mode to successfully scan hair.

The reason why Body Scan mode is so suitable to scan parts of the human body is that its alignment algorithm has been optimised to deal with non-rigid objects. It is thus usually referred to as non-rigid alignment.

This alignment mode, which is by default set to Feature Alignment, can deal with shapes that are likely to change, within a certain range. This is the case of human body, which moves due to the breathing or its inherent trembling.


  • For a better performance, wear clothes with low contrast. If the subject wears white and black colors, the operator will need to continuously adjust the brightness.
  • Since hair cannot be captured in good quality in this mode, wrapping the hair before scanning to prevent it from covering the body is advised.
  • Another option is to use dry shampoo to capture the hair better with this mode. 

Face Scan

Face Scan mode uses the Infrared light source for 3D scanning, which is suitable to scan the human face with an invisible projection avoiding subject's eye fatigue.

The Face Scan mode offers two aligning modes: Marker alignment and Feature alignment. The latter uses a non-rigid alignment.

Moreover, the Infrared light source from Face Scan mode helps capturing hair data. Some considerations are to be taken, which can be seen below.

Once you start a new work in Face Scan mode, some tips to successfully scan a complete person in Face Scan mode are provided.

Regarding the considerations to scan hair, please keep in mind not all haircuts are easy to scan.

Light needs to reflect on hair so the scanner can detect it. Therefore, spiky hair, the tips of the hair, thin tufts of hair... are difficult to scan since the light cannot reflect there. It is therefore advised to comb the hair to obtain a even, smooth surface:

The EinScan H integrated 3 scanning modes:

  • The Standard Scan mode: uses the LED source of light and is suitable for usual objects, ranging from 300 mm to 4 m.
  • The Body Scan mode: uses the LED source of light and its alignment algorithm is a non-rigid alignment based on features. It is therefore suitable to scan the human body. This mode cannot scan hair.
  • The Face Scan mode: uses the Infrared source of light and has two alignment modes. The feature alignment mode uses the non-rigid algorithm. Thanks to the invisible source of light, this mode prevents the subject eye fatigue and can deal with 3D scanning of hair.
