Construction Zone Sign Detection
First Claim
1. A method, comprising:
- receiving, at a computing device configured to control a vehicle, from an image-capture device coupled to the computing device, one or more images of a vicinity of a road on which the vehicle is travelling;
determining, using the computing device, one or more image portions in the one or more images, wherein the one or more image portions depict sides of the road at a predetermined height range;
detecting, using the computing device, a construction zone sign in the one or more image portions;
determining, using the computing device, a type of the construction zone sign in the one or more image portions;
modifying, using the computing device, a control strategy associated with a driving behavior of the vehicle, based on the type of the construction zone sign; and
controlling, using the computing device, the vehicle based on the modified control strategy.

Abstract
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.
