The Creaform EXAscan is a mobile handheld 3D scanner. This device uses lasers to scan the surface. It uses markers to determine its current position. Small circular reflective sticker markers need to be distributed randomly 8-10 centimeters from each other.
While in case of smaller objects it is sufficient to put markers only on the pedestal the object is on, in the case of larger objects markers should be distributed along the surface as well.
Advantages of the Creaform EXAscan:
Disadvantages of the Creaform EXAscan:
– Need to use markers
– In case the scanning enviroment changes (e.g. light conditions change) the scanner needs to be recalibrated
Laser scanning is usually used in reverse engineering.
