3D scanning compared tomanual anthropometry

Pro:

* Endless amount of body measures

* Shape, surface and volume measures

* No human variability in derived measures

* Scan can always be reprocessed

Contra:

* Costs and processing complexity


Overview of whole body 3D scanning systems

• Daanen HA, Van de Water, GJ. Whole body scanners. Displays 19: 111-120, 1998

• Rissiek A. Beam me up. Bekleidung Wear 52: 14-15, 2000.

• Simmons KP, Istook C. Comparison of three dimensional body scanners. Textile Magazine 30: 12-16, 2003

Short history of scanning systems

• Shadow scanners - LASS (1990)• Laser scanners - Cyberware, Vitronic (1994)• White light pattern scanners - TC2, Telmat (1995)• Millimeter wave scanners - Intellifit (2005)


Laser scanning techniques

• Cyberware WB4, X• Vitronic Vitus Pro and Smart• Hamamatsu• Hamano

Cyberware WB4



• Vitronic Vitus Pro (TNO)



• Pro’s:• Reliable proven technology• High quality and resolution• Many applications available

• Con’s:• Expensive• Slow (10-20 sec)• Cumbersome to transport


Scanners used in 3D scanning surveys

• Japan (about 1980) Nagano• France Lectra• UK (UK size) TC2-2T4• Netherlands (CAESAR) Vitronic Pro• Canada (CAESAR) Cyberware WB4• Italy (CAESAR) Cyberware WB4• US (CEASAR) Cyberware WB4• US (US size) TC2-2T4• Taiwan Vitronic Pro• Korea Cyberware WB4• Brasil Cyberware WB4


White light projection

• TC2 2T4, NX 12 and NX 16• Telmat• Inspec 3D• Wicks and Wilson Triform• NEC Danae 300• Unique Bodyskanner• Eyetronics (block projection)



• Pro’s:• Affordable• Geared to clothing applications

• Con’s:• Precision


Stereophotogrammetry

• Geodelta• Breuckmann• University Glasgow (Siebert)

Stereophotogrammetry

• Pro’s:• Extremely fast• Very inexpensive technology• Very promising technique for 3D scanning

• Con’s:• Software complexity• Hardly used


Millimeter waves

• Intellifit• TNO (no millimeter radiation source needed)


Millimeter waves

• Pro’s:• No need to undress (ease of use)• Fast

• Con’s:• No need to undress (privacy)• Low resolution• Expensive


Data processing

• Calibrate the scanner• Test the scanner using test objects

• Start scanning

• Align the scans• Merge the scans to one single object• Correct the errors (holes, topological errors)• Store raw and processed data


Clothing applications

• Sizing systems• Made-to-measure• Clothing fit evaluation


Clothing sizing system

• Sixteen charts for men

•Four stature groups: 168,176,184,192

•Four drop types: -15, -10, -5, 0

• Lectra

• Gerber

• Focus on graphics

• Poor fit validation
