Methods Scanning Systems

www.homometrica.chLaser scanning
Method:
Laser stripe projected onto the human body
Light sensor acquire the scene
Triangulation: distance projected line - sensor
To scan surface parts: displacement of line
Laser scanning system:
Laser beam
Optics
Light sensor
Displacement mechanism:optical, electromechanical, mechanical, free

www.homometrica.chModeling / image processing
Method:
Real 3D measurement is not performed
Image processing / modeling techniques are usedto gain 3D information from 2D images
Examples:
Body sizes measurementfrom two images
Realistic 3D face modelsfrom anthropometrical databaseand two photographs
Foot size measurement

www.homometrica.ch
2D Full Body Scanner (Human-Solutions GmbH)
Setup: 1 camera, 2 lights, calibration panel
