Embodiment 1

[0035] In order to solve the problem that the traditional traffic sign recognition technology is difficult to meet the needs of actual automatic driving, the present invention provides a traffic sign detection and recognition method embodiment 1; figure 1 It is a schematic flow chart of Embodiment 1 of the traffic sign detection and recognition method of the present invention; figure 1 As shown, the following steps may be included:

[0036] Step S110: process the traffic scene image to be recognized according to the preset HSV (Hue, Saturation, Value, hexagonal pyramid model) space color channel threshold value, and merge the specified HSV color channel to obtain the HSV space image of the traffic scene image to be recognized; According to preset SVF (Simple Vector Filter, simple vector filter) space color channel threshold value processing to be identified traffic scene image, and merge specified SVF color channel, obtain the SVF space image of waiting to identify traffic sce...

Abstract

The invention relates to a traffic sign detection identification method, apparatus and system. A sign plate region and a non sign plate region in a to-be-identified traffic scene image are segmented by comprehensive use of an SVF color space and an HSV color space, so that the influence of an interference color can be effectively eliminated; a color channel image is subjected to shape detection and locating, so that the detection of sign plates in multiple shapes such as a round shape, a triangular shape, a rectangular shape and the like can be realized, sign plate locating is realized, and identification types are added; and finally based on an image feature extraction algorithm, sign plate image features are extracted and transmitted to a trained preset classifier for performing sign plate classification judgment. The traffic sign plates erected above lanes or on two sides of a road can be detected and identified in real time in a running process of an intelligent vehicle; then an identification result is sent to a decision-making system of the intelligent vehicle; and the intelligent vehicle pre-judges a traffic condition in front of the vehicle in advance and makes response actions of reducing the speed, turning on a vehicle lamp and the like, thereby ensuring unblocked road and running safety of the intelligent vehicle.

Description

technical field [0001] The invention relates to the technical field of smart cars, in particular to a traffic sign detection and recognition method, device and system. Background technique [0002] At present, the traffic sign recognition systems developed by domestic and foreign enterprises or research institutes can be mainly divided into two categories: one is based on vision technology, which collects images of the surrounding environment of the vehicle through cameras, and then uses recognition algorithms to extract traffic sign related information in the images The second category is based on V2I (Vehicle to Infrastructure for short) technology, through the wireless Internet, temporary data exchange is performed between vehicles and road signs, so as to obtain traffic sign category information. [0003] During the implementation process, the inventor found at least the following problems in the traditional technology: the traditional vision technology-based solution is...
