Title: 2D Multiplier Method


1
Lecture 3
  • 2-D Multiplier Method

2
Plane of Motion
  • plane in which the motion occurs

3
Basic Requirement
  • plane of motion // image plane
  • Image similar to the object
  • Different scale

4
Calibration
  • Computation of the scale ratios
  • Reference ruler meter stick
