Abstract

The invention discloses a traffic sign recognition method and device and a vehicle, wherein, the method comprises the following steps: obtaining an image to be recognized by collecting an image in front of the vehicle; locating a traffic sign area in the image to be recognized according to color features and shape features of the image to be recognized; and obtaining SIFT features of the traffic sign area, and recognizing traffic signs in the traffic sign area according to the SIFT features of the traffic sign area. According to the method of the invention, the accuracy and the real-time property of the traffic sign recognition can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a traffic sign recognition method, a computer-readable storage medium, a traffic sign recognition device and a vehicle. Background technique [0002] With the increasing emergence of traffic safety issues, the research on intelligent assisted driving systems and unmanned vehicles has received more and more attention. Understanding the road traffic environment and obtaining real-time and accurate road traffic environment information are the main difficulties in the research of intelligent driving assistance. In the traffic environment, traffic signs provide important road traffic information and are important facilities for implementing traffic management and providing traffic behavior specifications for pedestrians and drivers to ensure smooth road traffic and driving safety. The automatic detection and recognition of traffic signs is an indispensable part of the traff...
