Metronor technology is built on in-house research and development inside electro-optics and photogrammetry – the science of precisely determining the location of items based on images.
All Metronor products have three main components:
- A set of light sources, typically very robust and reliable Light Emitting Diodes (LEDs)
- One or more solid-state digital cameras, capturing images of the LEDs
- A computer, automatically controlling and optimizing the LED and cameras interaction
The LEDs are typically mounted into a structure such as a hand-held probe, and form a stable pattern. If the shape and size of the LED pattern is known, then a single image of the LED pattern is enough to calculate where the LED pattern is relative to the camera – both in terms of position as well as orientation.
Some unique aspects of Metronor technology:
- Completely solid state without moving parts – rugged, reliable, stable/accurate over time.
- Redundancy – designed to acquire more data (minimum 5 LEDs when 3 is minimum requirement) than needed in order to verify measurement accuracy continuously – bad data is worse than no data.
- Modular – easily upgraded, flexible investment, excellent supportability
- Remote, stationary sensor – no forces acting through camera/tripod, so no need to anchor or weigh down to try to eliminate effects of probe movement like on measurement arms.
