Road traffic sign recognition method and device

Abstract

The embodiment of the invention discloses a road traffic sign recognition method and device. The method includes the steps of obtaining a to-be-identified image which is pre-marked with the type information which is to-be-identified road traffic sign type information, determining a to-be-identified area in the to-be-identified image according to the type information; identifying the to-be-identified area, and determining the road traffic signs contained in the to-be-identified area. The to-be-identified image pre-marked with the type information is acquired, so that the automatic identification of the road traffic signs can be realized, and the identification speed is higher. The updating period of the road traffic sign information is shortened, and the updating efficiency is improved. Different types of signs are marked on to-be-identified images in advance, and different recognition schemes can be used for identifying the road traffic signs according to different types of to-be-identified images. The road traffic signs are recognized through different channels, and the recognition efficiency of different road traffic signs is effectively improved.

Description

technical field [0001] The invention relates to the technical field of map data processing, in particular to a method and device for identifying road traffic signs. Background technique [0002] Road traffic sign is a sign used to remind road users of information such as warnings, prohibitions, restrictions or instructions.
