Abstract

The invention belongs to the technical field of driverless vehicles, and particularly relates to a traffic signal lamp identification system based on a video signal image processing technology and anidentification method thereof. The system comprises a vehicle-mounted front camera, an Image recognition device, a Voice chip, a loudspeaker, an accelerator pedal and a brake; an image recognition device is used for judging a signal acquired by the vehicle-mounted front camera; The image recognition device is composed of color recognition, shape recognition, shape secondary confirmation and continuous image recognition result verification, and images collected by the vehicle-mounted front camera are recognized in a double-rail mode based on RGB space on the whole and locally recognized based on HSL space. The traffic signal lamp identification method provided by the invention is simple and efficient, the identification result is confirmed and verified for multiple times, the reliability isvery high, experiments show that the design method is high in accuracy, has the capability of detecting the traffic signal lamp in real time, and can meet the working requirement of traffic signal lamp identification under the actual road traffic condition.

Description

technical field [0001] The invention belongs to the technical field of unmanned vehicles, and specifically relates to a traffic signal light recognition system based on video signal image processing technology and a recognition method thereof. Background technique [0002] With the continuous development of my country's economy and society since the reform and opening up, automobiles have become increasingly popular, which has brought great convenience to people's lives and also brought many problems, the most prominent of which is the number of casualties caused by frequent traffic accidents constant increase. Traffic accidents are mainly caused by human factors such as insufficient skills of drivers, violations of rules and regulations, and fatigue driving. Therefore, reducing the negative impact caused by drivers' misjudgment and misoperation is an effective measure to improve road safety. [0003] As a part of modern urban road traffic lights, traffic lights are an impor...
