Short History of 3D Scanning

• 1850’s Photogrammetry. Basically as soon as photography was invented then methods use the photographs were developed to interpret distances

• 1950’s: First came the Touch or Contact Probe aka CMM Coordinate Measuring Machine. 1st commercial unit introduced in Britain in 1951.

• 1980’s- early 1990’s: Some of the first light scanners became available . One of the first applications was capturing human forms for the animation industry.

• Mid 1990’s: Early commercial units became available in the mid 90’s. They were very costly $250K+ requiring high end computer hardware to operate Unix Workstations $50-100K. Manual operation. Operators would take still shots then merging all scans into a single point cloud, editing it to remove all holes, noise and flaws, then surfacing or spline sectioning the point cloud automatically or semi-automatically

• 2000’s: With the usual cost of technology dropping the main development focus has been on improving the intermediate steps required to get the data from the scanner to a complete 3D model, including direct importation of the point cloud data into CAD systems such as SolidWorks and ProE.

• Over the last 10-15 years there has also been much commercial effort to develop fully automated systems. These are the first automated inspection systems.

Types of 3D Scanning Tech

• Photogrammetry• CMM (Contact)• Cross Sectional (Destructive)• Non Contact

• Laser, White Light, LIDAR (Time of Flight)





Why 3D Scan?

• Reverse Engineering• Metrology• Museology - Store records• Multimedia – Games and Movies





Technology of 3D Scanning

Types of Non-Contact Scanning Technologies

– Triangulation– White Light– Time of Flight





Technology of 3D ScanningTRIANGULATION• Emits a laser light• Uses Sensors(Camera) to read Laser Crosshairs• Uses the principles of a Triangle to calculate distance and

position• Uses Reflective Targets for positioning • Two Types of Systems

– Optical Profilometer, fitted on an arm– Portable 3D Scanner

CONS• Line of Sight, Viewing Cone• Range (12”-15”)

PROS• Accuracy • Speed





Technology of 3D ScanningWHITE LIGHT SCANNING• Emits a Polarized light pattern or a Coded light pattern • Uses Sensors(Camera) to read returning patterns of light• Uses the principles of a Triangulation and Photogrammetry to

calculate distance and position• Decodes returning patterns of light to digitize object• Two Types of Systems

– Polarized Light Pattern (Fixed)– Coded Light Pattern (Handheld)

PROS• Range (within 3ft. or further from object)• Speed • Accuracy

CONS• Range (within 3ft. or further from object)• Part must be White





Technology of 3D ScanningTIME-OF-FLIGHT SCANNING• Uses Laser range finder to measure one point at a time• Calculates position using the Speed of Light theory• Used to scan long range applications

PROS• Large Range

CONS• Rigidity • Speed • Accuracy (within mm)• Noisy Data





3D Scanning

CREAFORM REVSCAN• Entry-Level Scanning System• Accuracy: 0.002”• Resolution: 0.004”• Range: 12”• Field of View: 8”x8”

• 3D Laser Scanner• Uses Triangulation• Reflective positioning Dots• Very Portable• Flexible

What’s Really Happening with Positioning Targets?





3D Scanning

SCANNER PREPERATION

Calibration• Calibrates Sensors to a Standard• Uses Calibration Plate• 14 Steps





3D Scanning

Configuration• Configures Laser & LED Intensity• To each Part Surface color





3D Scanning

Things to note during Demonstration

• Crosshairs• Data Collection





3D Scanning


• Crosshairs• Sharp Corners

• Hard to Get data





3D Scanning


• Crosshairs• Sharp Corners• Noise

• Sharp Corners• Shiny Surfaces• Some other reason





3D Scanning


• Crosshairs• Sharp Corners• Noise• Triangulation

• Can’t see it, Can’t scan it





3D Scanning


• Crosshairs• Sharp Corners• Noise• Triangulation• Half way there

• Post Processing





3D Scanning


• Crosshairs• Sharp Corners• Noise• Triangulation• Half way there• Thin Sections
