The present invention relates to a
road traffic sign identification method with multiple-camera integration based on the DS evidence theory, belonging to the technical field of
image processing. According to the method, five
types of road traffic indication signs which are going straight, turning left, turning right, going straight and turning left, and going straight and turning right are mainly identified, and the method is divided into two parts which are training and testing. In a training stage, the direction gradient
histogram feature of a training sample is extracted, thus a sample characteristic and a category
label are introduced into a
support vector machine to carry out classification training. In a testing stage, an interested region is obtained through image pre-
processing, the direction gradient
histogram feature of the interested region is extracted and is sent into a classifier to carry out classification, according to the credibility of the sign to be identified obtained by the classifier belonging to each category, and combined with a DS evidence theory
data integration method and a maximum credibility
decision rule, a final sign identification result is determined. According to the invention, a multiple-camera
data integration method based on the DS evidence theory is employed, the information of multiple cameras are integrated to obtain a final identification result, and the
road traffic signs can be stably and efficiently identified.
