  1. 3D Theory

  2. Visualiner 3-D • No Electronic Heads • No Target Calibration • No Runout Compensation, Jacking, or Jouncing during Measurement of Alignment Angles • Fastest Aligner Ever • Most Accurate Aligner Ever • Easy to Use

  3. Maintenance ? N • Cables to the heads • Batteries • Light Beams Blocked while under the car • Sensitive Heads • Accuracy Problems • Lengthy Alignment Time • Jacking the Vehicle for Run-out • Heavy Wheel Sensors

  4. 3-D Aligner - The Idea • An Engineer in San Jose, CA saw a car that had an obvious wheel alignment problem • IDEA … can a “machine” see and determine alignment angles like the human eyes and brain? • YES … using cameras and computers!!!

  5. Wheel Targets Wheel Targets Camera Field of View - Top View SM8

  6. Photo-lithography 3-D Design Theory • The LED light is very bright • Only the LED light is used (filtered) • Each time the LED’s flash a camera image is captured. • The LED’s flash approximately 2 times per second • Target Circles are etched with a process called: Camera Pod

  7. Perspective for Measuring Distances When an object is moved away it appears to get smaller If we no the actual size of the object(target) we can calculate the distance from the camera to the target or from target to target

  8. Fore Shorting For Measuring Angles 2 Dimensions When an object is tilted it appears to get smaller

  9. Why Circles? As the circle is moved away distance is measured

  10. And... As the circle is rotated it forms an ellipse This ellipse is used to measure the angle of the Target

  11. Perspective Toe Distance Caster Change Camber 3-Dimensions Fore Shorting The angle of the vector is used to determine the Camber Angle

  12. Rolling Radius Tire Outside Diameter... can be calculated from degrees of rotation compared to the distance it moves

  13. Postioning/Rollback When the Camera looks at the Target the circles form a Vector Line This Vector will rotate around the spindle axis during Positioning/Rollback Top View
