How it works

Laser Triangulation

3D Vision Technology - Laser Triangulation - Zivid

Principles

  • Laser line triangulation
  • Displacement of laser line on objects in scene is proportional to object height.

Key considerations

  • Laser light source, robust to ambient.
  • Simple measurement principle.
  • Highly customizable.
  • Good fit for conveyor applications.
  • Slow since it requires scanning motion across the scene.
  • No color information.
