TRAFFIC LIGHT DETECTION DEVICE AND TRAFFIC LIGHT DETECTION METHOD

Title:

TRAFFIC LIGHT DETECTION DEVICE AND TRAFFIC LIGHT DETECTION METHOD

Document Type and Number:

WIPO Patent Application WO/2016/162975

Kind Code:

A1

Abstract:

A traffic light detection device uses an image pickup unit mounted on a vehicle to extract, from an image taken of surroundings of the vehicle, synchronized pixels (DA1 to DA3), the brightness of which changes in synchronization with an alternating current period of electric power supplied to a traffic light, and detects the traffic light from the synchronized pixels. The traffic light detection device is provided with: a positional variation calculation unit for calculating positional variation amounts (G1 to G3, g1 to g3) of continuously extracted positions of the synchronized pixels; and a signal lamp determination unit for determining, as a signal lamp candidate, the synchronized pixels of which the positional variation amount is equal to or smaller than a threshold value.
