Traffic signal lamp identifying system and method

Abstract

The invention provides a traffic signal lamp identifying system. The system comprises an image acquisition module for acquiring images, a traffic signal lamp detecting module, a traffic signal lamp classifying module, a traffic signal lamp status identifying module and an identification information output module, wherein the traffic signal lamp detecting module detects whether a traffic signal lamp is in an image or not, records the area position and size of the traffic signal lamp if the traffic signal lamp is in the image; the traffic signal lamp classifying module cuts one or more traffic signal lamp areas in the image which is detected to contain the traffic signal lamp according to the area position and size, analyzes the cut traffic signal lamp areas, and determines the classification of a current traffic signal lamp; the traffic signal lamp status identifying module analyzes and identifies color information of the traffic signal lamp area, and determines the status of the traffic signal lamp according to the color information and the classification; and the identification information output module generates corresponding prompt information according to the identified status of the traffic signal lamp. The traffic signal lamp identifying system has a good assistant effect for drivers and achromates.

Description

【Technical Field】 [0001] The invention relates to the field of traffic, in particular to a traffic signal lamp identification system and method. 【Background technique】 [0002] Traffic signal lights are an important device to ensure traffic safety and keep roads open. At present, the commonly used traffic lights rely on three colors of red, yellow, and green to indicate traffic. According to Chinese law, people with color blindness are prohibited from driving motor vehicles for life. The main reason why color-blind people are prohibited from driving is because there are many red-green blindness among color-blind people, and the colors they see are different from those of non-color-blind people. Therefore, the color-blind person's incorrect recognition of the color of the traffic signal while driving may bring great danger. With the continuous development of my country’s economy and the continuous improvement of people’s living standards, the number of motor vehicles has increa...

Therefore, the incorrect recognition of the color of traffic lights when driving by a color-blind person may pose a great danger

With the continuous development of our country's economy and the continuous improvement of people's living standards, the number of motor vehicles has increased rapidly. However, due to the restrictions on the color of traffic lights, it has brought a lot of inconvenience to the travel of color-weak/color-blind people, making it even more impossible for them to drive motor vehicles.

[0003] Chinese utility model CN2919406 discloses a traffic light that can be recognized by color-blind people, which keeps the main structure of the existing traffic light unchanged, and only changes the shapes of the lampshades of the red and green lights, that is, the shapes of the lampshades of the three lights are different , so as to enable color-blind people to recognize traffic lights, but this traffic light changes the
