  14. 14.  Lasers to project on to human body one or more thin and sharp strips simultaneously. Light sensors acquires the scenes and by applying simple geometrical rules the surface of human body is measured. The laser scanner unit, which is composed of the laser, the optical system and the light sensor, ismoved across the human body to digitize the surface.
  15. 15.  FULL BODY SCANNER Vitus (VITRONIC GmbH). 4 scanner units moves vertically along 4 pillars Total scanning time: ~ 12 seconds.
  16. 16.  FULL HEAD SCANNER 3030RGB/PS (Cyberware Inc.) 1 scanner unit moves horizontally in circle around a person Total scanning time: ~ 17 seconds.
  17. 17.  FULL FOOT SCANNER YETI (Vorum Research Corp.) 3 scanner units moves horizontally along the foot Total scanning time: ~ 4 seconds
  18. 18.  Quickly capture all of the physical measurements of any physical object Save time in design work Ensure parts will fit together on the first try. enhancing a products design accurate measurements of an object.
  19. 19.  Cost. Laser is harmful. Psychological factors , nudity. Practical problems like moment, breathing , hairs , eyes. Private data – visibility & data storage.
  20. 20.  It is second technology used extensively for human body measurement. Instead of moving the scanner unit, a light pattern (usually in form of stripes) is projected onto the human body. binary coding are used to determine the origin of the single stripes; for the increment of the resolution, the projected stripes are additionally shifted.
  21. 21.  Less time for scanning No harmful for body-eye safe Comparatively more accurate Economical factor Creates a very high density point cloud Can scan small parts with intricate details
  22. 22.  Sensitive to ambient light – best used in darkened room Cannot be used to scan shiny surfaces “Occlusion” effects require the need for additional images to be taken Slow when measuring objects with many intricate details

  24. 24. FULL BODY SCANNER Mega 3P (InSpeck Inc.)3 pillars placed around a personEach pillar has 2 sensor units: projector and cameraTotal scanning time: ~ 4 seconds
  25. 25. In this technology, 3D measurements are not performed, but3D information is generated and extracted from 2D images.By using the symmetry of the human body, the mostimportant sizes of body are computed with sufficientaccuracy from the silhouettes of the body.The big advantage of combining image processing andmodeling techniques is the extremely lower price comparedto real 3D measurement
  26. 26. Full body scanner Intellifit System (Intellifit Corp.,Unique Ltd.) (2005) Person step inside the cabin without undressing “L” shaped mm-waves transceiver swings around the person
  27. 27.  Non-harmful radiation penetrates clothing and reflects off the body. The reflected signal are recorded by the transceiver and analyzed. 200,000 points of body surface measured Body sizes extracted automatically, accuracy: 6mm
  28. 28.  The method combines classical human body measurement and digital technology. The measurement process is completely similar to classical tape measurement, where lengths are measured by a tape at different key-location of the human body (chest, waist, sleeve, etc.).
