Lessons learned for making 3D scanning usable by the general public

3 different cases - Feet, Faces and Joints

Goal Best practices for 3D scanning technology to solve human measurement problems Understand value proposition of moving 3d scanning from back-end systems Discuss risks and pitfalls Tackle production issues

Best practices for 3D scanning technology to solve human measurement problems

Understand value proposition of moving 3d scanning from back-end systems

Discuss risks and pitfalls

Tackle production issues

Key Issues 1 Scanning humans has different requirements than mechanical parts Movement 3D scanning working outside of controlled settings Used by untrained and non-technical operators Scanning speed and robustness

Scanning humans has different requirements than mechanical parts

Movement

3D scanning working outside of controlled settings

Used by untrained and non-technical operators

Scanning speed and robustness

Key Issues 2 The cost factor is challenging Competition is traditional tools better, faster, or cheaper Digital solutions has different trade offs versus traditional tools Overcoming social fears

The cost factor is challenging

Competition is traditional tools

better, faster, or cheaper

Digital solutions has different trade offs versus traditional tools

Overcoming social fears

Methodology Custom build 3D scanners for each particular application Scanners prototyped and tested with end-users every step of the way Adapt available technologies, mix and match old and new techniques Modify the parameters of the problem

Case Study 1 – Feet Semi-custom to fully custom orthotics Scanning feet Plaster cast and foam replacement Simple value proposition. Plaster and foam requires more time and physical handling costs Digital scanning is simple, clean and fast

Semi-custom to fully custom orthotics

Scanning feet

Plaster cast and foam replacement

Simple value proposition. Plaster and foam requires more time and physical handling costs

Digital scanning is simple, clean and fast

Case Study 1 – Lessons Learned Scans asked to be highly reduced High data sets = more storage, processing, and transmission time Less is more. The right measurements, not more measurements Scans data are used to look up into a model library, additional data is not needed Accuracy requirements are low. Ease of use requirements are high Time is money. Faster is better

Scans asked to be highly reduced

High data sets = more storage, processing, and transmission time

Less is more. The right measurements, not more measurements

Scans data are used to look up into a model library, additional data is not needed

Accuracy requirements are low. Ease of use requirements are high

Time is money. Faster is better

Case Study 2: Lessons Learned There will be holes in a single scan Solutions: Automatic - hole filling Use replacement parts (No ears? No problem) More cameras or scanners Glasses can be an issue Hair in general does not scan that well Even if data is captured, a polygon mesh represents hair poorly In visual effects or games you would replace with a hair simulation For manufacturing, mesh may be okay

There will be holes in a single scan

Solutions:

Automatic - hole filling

Use replacement parts (No ears? No problem)

More cameras or scanners

Glasses can be an issue

Hair in general does not scan that well

Even if data is captured, a polygon mesh represents hair poorly

In visual effects or games you would replace with a hair simulation

For manufacturing, mesh may be okay

Case Study 2: Lessons Learned White light and laser safety Rated to be safe People are very skeptical, especially athletes Faces are the hardest thing to keep “still” Different industries Visual effects, artists want to do lots of editing, can deal with lots of polygons For manufacturing, take the face or head scan and blend it in to a pre-existing model for less cleanup

White light and laser safety

Rated to be safe

People are very skeptical, especially athletes

Faces are the hardest thing to keep “still”

Different industries

Visual effects, artists want to do lots of editing, can deal with lots of polygons

For manufacturing, take the face or head scan and blend it in to a pre-existing model for less cleanup

Case Study 3 – Joints Bracing Products Knees Elbows Ankles Data acquisition from multiple directions

Bracing Products

Knees

Elbows

Ankles

Data acquisition from multiple directions

Case Study 3 – Lessons Learned A fast 360 may requires multiple cameras Systems that sweep around the joint will work While humans are not rigid, general shape remains unchanged Automated alignment can be challenging

A fast 360 may requires multiple cameras

Systems that sweep around the joint will work

While humans are not rigid, general shape remains unchanged

Automated alignment can be challenging

End User Issues People don’t know what to expect There is significant reluctance and fear People worry about being digitally “copied” especially women Social fears to the 3D scanning like early photographers Everyone moves all the time Faster, higher cost, higher quality scanners Support the persons (Wall, chairs) Live with the noise

People don’t know what to expect

There is significant reluctance and fear

People worry about being digitally “copied” especially women

Social fears to the 3D scanning like early photographers

Everyone moves all the time

Faster, higher cost, higher quality scanners

Support the persons (Wall, chairs)

Live with the noise

Lessons Learned Plan your scanner output to match required manufacturing input Fully automated solutions are difficult, but worth the effort Robustness is critical 100% coverage near impossible New methods will rarely be “cheaper” than old methods. The ability to digitally measure, analyze and deliver data is valuable

Plan your scanner output to match required manufacturing input

Fully automated solutions are difficult, but worth the effort

Robustness is critical

100% coverage near impossible

New methods will rarely be “cheaper” than old methods.

The ability to digitally measure, analyze and deliver data is valuable

Easy Wins 3D scanning is “cool”’ Value proposition is straight forward Existing solution is error prone, slow, difficult, and requires shipping Digital solution is fast, accurate and can be digitally delivered Accuracy requirements are orders of magnitude lower than manufacturing

3D scanning is “cool”’

Value proposition is straight forward

Existing solution is error prone, slow, difficult, and requires shipping

Digital solution is fast, accurate and can be digitally delivered

Accuracy requirements are orders of magnitude lower than manufacturing

Future Steps Making simple and robust “1-click” scanning systems Look for end to end value, not just 3D scanning Develop digital measurement, analysis and information delivery platforms. Get more correct measurements more easily at a lower cost
