Feature Alignment - Shining 3D EinScan Pro HD User Manual

If the object's diameter is smaller than 150mm, it will not cover most coded targets
on the turntable surface. Place the object on the middle of the turntable and make
sure it will not shake or move during the rotation.

Feature Alignment

When the object you need to scan is big and will cover most coded targets on the
turntable, and you do not want to or cannot stick markers on it, then feature
alignment will be helpful. With feature alignment, the software recognizes geometry
features on three successive preliminary scans and then calculates the position of the
turntable. The scans are matched by knowing the center and angle of rotation
between successive captures.
An object with simple features like plain, symmetric surface such as a sphere or
cylinder is not recommended for this mode. It is better to use markers to facilitate
the alignment for an object with few geometry features.
Using feature alignment, make sure that the object is kept still on the turntable, and
the first view should contain enough features to allow the initialization.
