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.
