Abstract
A system to detect LEDs and their states in an AR context is provided having a monitored device having a plurality of LEDs; a computer receives a picture of the monitored device and LEDs; the computer processes said picture to determine a plurality of feature points; a database is in data communication with said computer that stores a plurality of reference images with reference feature points and reference zones; the computer matches at least some of the plurality of feature points with at least some of the plurality of reference feature points to compute a homography matrix; the computer transforms the picture into a transformed picture using the homography matrix; the computer processes zones of the transformed picture based on the reference zones to determine the state of each of the plurality of LEDs by comparing a value of the picture in the zone with a reference value.
