An image-based traffic signal recognition device and method

Abstract

The present invention provides an image-based traffic signal light identification device and method. The vehicle-mounted camera pre-photographs traffic signal light images when the vehicle is traveling at different speeds and stores them in the sub-library of the signal light image storage module. Each sub-gallery is identified by speed; The image in front of the vehicle is captured by the on-board camera of the image real-time acquisition module during vehicle driving, and the image is passed to the suspected signal light area extraction module; the suspected signal light area extraction module receives the image collected by the image real-time acquisition module, and extracts red, yellow and green in the image All highlighted areas of the signal light area, and determine whether it is a suspected signal light area; the image matching module calls the corresponding sub-library in the signal light image storage module according to the current vehicle speed fed back by the driving speed feedback module, and compares the graphics in the suspected signal light area with the corresponding The images in the sub-gallery are matched; the language module receives the matching results of the image matching module and plays corresponding language prompts to the driver.

Description

technical field [0001] The invention belongs to the technical field of image recognition, and in particular relates to an image-based traffic signal lamp recognition device and method. Background technique [0002] At present, automobile assisted driving is in a period of vigorous development. Automobile assisted driving refers to the intelligent identification of road conditions through the electronic equipment of the automobile assisted driving system in automobile driving engineering, and assists the driver to drive the car. [0003] During the driving process of the car, the vehicle assisted driving system is indispensable for the identification of road traffic lights. At present, there are a large number of existing technologies for traffic signal recognition, and the recognition technology for traffic lights above the suspended road has become increasingly mature. [0004] However, in some road construction sections, in order to maintain traffic order, the traffic depa...

Problems solved by technology

[0004] However, in some road construction sections, in order to maintain traffic order, the traffic department will set up temporary traffic lights beside the road. This type of traffic lights is often very short, less than 3 meters in height. Tail lights and other light sources are mixed together, making it difficult for the car's auxiliary driving system to correctly identify
