Both Linear and Static Metric Calibrations have some advantages and disadvantages. This pros and cons tables will help decide which is the most convenient calibration system for each project.

Static Metric Calibration Pros and Cons
Pros Cons
  • Only one frame needed
  • Robust to conveyor vibrations
  • Allows other set-ups different than a conveyor (e.g. rotating, robot arm...)
  • Simplier and cheaper calibration pattern
  • Less accurate due to less calibration points
  • Vertical laser limitation: precision on the 90ยบ angle required
Linear Metric Calibration Pros and Cons
Pros Cons
  • More precision due to more calibration points
  • Allows non-vertical laser configurations
  • Multiple laser line detection with one single camera supported to avoid occlusions
  • Calibration pattern also compatible with the Merger Tool
  • Precision on the synchronization with the conveyor trigger required
  • More complex and expensive calibration pattern
  • Sensitive to conveyor vibrations
