Problems solved by technology

Most of the accidents were caused by drivers driving recklessly and not obeying traffic rules. A large part of them were caused by drivers crossing two lanes during driving. Among them, whether the vehicle is on the line or not depends entirely on the driver's driving experience, which is extremely inaccurate

Abstract

A lane departure warning system based on machine vision, including an interface processing unit, a front-view camera, a digital signal processing unit, and a power supply module. The location of the car, collects the image in front of the car, and transmits the image to the digital signal processing unit. The digital signal processing unit intelligently decides whether the vehicle is about to deviate from the lane. The image information processed by the digital signal processing unit is transmitted to the interface processing unit, and the interface processing unit controls The alarm device works, and the power module supplies power to other modules. It uses advanced visual pattern recognition algorithm, combined with a high-speed digital signal processor to analyze the driving conditions of the camera installed on the car, and can send a visual signal to the driver when it is predicted that the vehicle will deviate from the lane, but the driver does not actually do so consciously. , Audible or tactile warnings to remind drivers to pay attention to safe driving and effectively reduce accidents.

Description

technical field [0001] The invention discloses a vehicle warning system, in particular a machine vision-based lane departure warning system and method. Background technique [0002] With the gradual development of the automobile industry, the number of automobiles is increasing day by day. The convenience and speed that automobiles bring to people's lives is self-evident. The vigorous development of the automobile industry has brought great contributions to the economy, but it has also produced a series of social problems, among which traffic accidents are the most serious problem. According to statistics, there were 210,812 cases and 62,387 deaths in China in 2011. Most of the accidents were caused by drivers driving recklessly and not obeying traffic rules. A large part of them were caused by drivers crossing two lanes during driving. Among them, whether the vehicle is on the line or not depends entirely on the driver's driving experience, which is extremely inaccurate. ...
