ScanWorks?
What is Laser Triangulation?

• Project a flat plane of eye-safe, tuned laser
  light
• Capture the reflection from the object with a
  camera
• Process data using AutoSolve Algorithms

ScanWorks sensors incorporate a solid state laser
diode utilizing precision mirrors to create a
precise laser line no moving or oscillating
mechanisms

What are typical questions asked about laser
scanners?
ScanWorks?

• How does light affect the laser sensor?
• How does surface texture and finish affect the
  laser scanner?
• How does color affect the laser scanner?
• How do temperature and environmental conditions
  affect the laser scanner?
• What are the accuracy, resolution, repeatability,
  and pixel spacing of the laser scanner?
• Is there a recommended calibration and
  maintenance procedure for the laser sensor?
• Are there concerns for eye safety?

10
ScanWorks?

• How does light affect the laser sensor?
• The types of lighting in lab, studio, and factory
  environments can effect an optical device. While
  some types of scanning devices such as
  white-light and photogrammetry must have a
  light-controlled environment, this is not the
  case for ScanWorks sensors
• Why? Perceptron sensors use an optical filter
  which is designed to reject all wavelengths of
  light except those near the laser being used.
  Thus, light from incandescent, mercury vapor,
  halogen and other popular lighting systems are
  rejected by the filter

11
ScanWorks?

• How does surface finish affect the laser scanner?
• Measurement accuracy will be affected by surface
  finish. Highly polished chrome and shiny black
  surfaces are the most difficult to scan. But
  these and colors in between cause problems for
  many laser line and white-light scanners
• In such cases, a coating of powder spray is
  necessary to make the surface scan friendly.
  While most other laser line scanners and
  white-light scanners require this powder spray
  coating, ScanWorks sensors typically do not
• Why? ScanWorks sensors utilize industry proven
  tools built into the scanner software to adjust
  the exposure and threshold, which can help in
  compensating for most surface conditions

12
ScanWorks?

• How does color affect the laser scanner?
• Color can affect an optical devices ability to
  scan the surface. Many laser line scanners have
  difficulty if the surface contains multiple
  colors
• ScanWorks sensors have been measuring automotive
  vehicles in the finished state for years in the
  assembly plants so the same industry proven tools
  are built into the scanner software which can
  help in compensating for most color conditions

13
ScanWorks?

• How do temperature and environmental conditions
  affect the laser scanner?
• Typical plant environments are acceptable to the
  operation of the scanner. The scanner is not
  suitable for direct water or oil spray
  environments. The temperature should be between
  15 and 35 C and the humidity between 0 and 90
  non-condensing

14
ScanWorks?

• What are accuracy, resolution, repeatability, and
  pixel spacing of the laser scanner?
• Each ScanWorks sensor has a 3-sigma value for
  accuracy, resolution, and repeatability and comes
  with a NIST traceable certificate
• System accuracy depends upon the moving device
  portable arm, CMM, robot, or other device

15
ScanWorks?

• Is there a recommended calibration and
  maintenance procedure for the laser sensor?
• The sensors are calibrated (rectified) at
  Perceptron upon assembly. Under normal usage,
  there is no need to re-calibrate the sensor. In
  fact, in the Perceptrons systems side, sensors
  are used 24/7 for 10 years without the need for
  re-calibration. If the sensor is dropped or
  damaged, calibration will be required.

16
ScanWorks?

• Are there concerns for eye safety?
• The Perceptron scanner is rated a class IIm laser
  which means it is eye safe and does not require
  special protection or shielding

ScanWorks

• 4 Major Categories
• Inspection / Validation
• Produces 3D point cloud for cloud-to-CAD
  comparison, feature recognition for dimensional
  inspection, and GDT analysis
• Reverse Engineering
• Produces a CAD model that describes a sample
  part. RE software is used to import a scanned
  point cloud, and than mathematically smooth and
  combine the scan data until representative NURB
  surfaces are generated
• Rapid Prototyping
• Produces a duplicate of a sample part from a CAD
  representation of the part. This represents a
  combination of reverse engineering and copying
• Copy Milling
• Produces a duplicate of a sample part directly
  from the scan cloud data. CAM (Computer Aided
  Manufacturing) is used to read the scan cloud
  data and produce machining instructions for CNC
  tools

29
ScanWorks
Inspection / Validation

• Verify that manufacturing meets CAD
• Incoming inspection pass-fail condition
• Check for interference conditions between product
  material and process variables in part
  manufacturing
• Perform root cause analysis of defects in a
  product, process, design issues to determine
  where and from what influences fit and
  dimensional compliance
• Perform 100 part surface capture
  comparison-to-design reference (CAD) vs. a
  traditional inspection via CMM, fixture gage, and
  hand tools
• Verify tool / die re-work at station for quicker
  turn around
• Presence / absence of parts in an assembly
• Contour Measurement
• Compare part contours to their corresponding CAD
  models
• 2-D cross sectional cuts
• 3-D part topographical mapping
• GDT analysis
