Construction Zone Sign Detection

摘要

Methods and systems for detection of a construction zone sign are described. A computing device, configured to control the vehicle, may be configured to receive, from an image-capture device coupled to the computing device, images of a vicinity of the road on which the vehicle is travelling. Also, the computing device may be configured to determine image portions in the images that may depict sides of the road at a predetermined height range. Further, the computing device may be configured to detect a construction zone sign in the image portions, and determine a type of the construction zone sign. Accordingly, the computing device may be configured to modify a control strategy associated with a driving behavior of the vehicle; and control the vehicle based on the modified control strategy.

主权项

1. A method comprising:
receiving, at a computing device configured to control a vehicle, from an image-capture device coupled to the vehicle, an image of a vicinity of a road on which the vehicle is travelling; selecting, from the image, using the computing device, an image portion corresponding to a side of the road at a predetermined height; detecting, using the computing device, a construction zone sign in the image portion; determining, using the computing device, a type of the construction zone sign; detecting one or more construction zone objects on the road; determining, based on a number and locations of the one or more construction zone objects, a severity of road changes; and controlling, using the computing device, the vehicle based on (i) the type of the construction zone sign, and (ii) the severity of road changes.
