Driving assistance system based on signal lamp information prompts

Abstract

The invention discloses a driving assistance system based on signal lamp information prompts. The system includes a data acquisition and preprocessing module, a traffic light and countdown information detection and identification module, a distance and speed calculation module and a control module, wherein the data acquisition and preprocessing module, traffic light and countdown information detection and identification module and distance and speed calculation module are connected with the control module. In a signal lamp road segment, according to an image obtained by a front camera of a vehicle, the driving assistance system identifies traffic light and countdown information, calculates distance from the vehicle to signal lamps, predicts time when the vehicle arrives at a stop line, and gives a corresponding operation prompt to a driver, thereby improving driving safety, and reducing occurrence of traffic accidents.

Description

technical field [0001] The invention relates to a driving assistance system based on signal light information prompting, in particular to identifying signal light information, calculating distance and predicting the time when the vehicle arrives at the signal light intersection through image processing technology in a traffic signal light road section, and prompting the driver to make corresponding operations. Background technique [0002] With the development of urbanization and the acceleration of automobileization, automobiles have become an indispensable means of transportation for people to travel. With the continuous increase of car ownership and the acceleration of application popularization, traffic congestion and traffic accidents for various reasons are also becoming more and more serious. Traffic lights have become the most common and effective means of diverting traffic. The emergence of traffic lights enables effective traffic control, which has obvious effects...

AI Technical Summary

Problems solved by technology

However, in many cases, due to the driver's wrong estimation of the time to reach the stop line of the signal light, and the bad driving habits of some drivers, traffic accidents are extremely prone to occur at the signal light intersection when the signal is exchanged (green light turns red light)

However, many existing driver assistance systems only prompt whether there are traffic lights ahead according to the existing database information, but do not prompt the current real-time signal light information and cannot provide real-time help to the driver.
