Traffic Light Detection Using High-speed Vision


Automatic traffic light detection plays an important role for driver-assistance system and autonomous vehicles. Based on the fact that LED traffic light flashes in proportion to the input AC power frequency, we propose a traffic light detection method which focuses on the flash pattern extraction using high-speed vision. Exploiting temporal information is shown to be very effective in the experiments. It is considered to be more robust than visual information-only methods.
