Mountain highway curve blind area automobile meeting early warning system based on panoramic camera technology

Abstract

The invention discloses a mountain highway curve blind area automobile meeting early warning system based on the panoramic camera technology. The system comprises an image acquisition module, an image processing module and a control module. The image acquisition module is for timely acquiring images at left and right entrances of a curve and in the curve. The image processing module is for receiving an image signal and processing an image. A vehicle identification module is for identifying a vehicle and determining the movement direction of the vehicle. The control module is for outputting a corresponding control instruction according to an output result of the vehicle identification module, so as to control a signal output display module to whether output specific image information or not. The system can timely detect traffic information at the curve entrance, in the curve and at the curve exit, so that an early warming prompt can be provided for drivers who will soon enter the curve, and the driving safety is improved.

Description

technical field [0001] The invention belongs to the technical field of vehicle detection and road traffic safety, and in particular relates to a vehicle meeting warning system in a blind spot on a mountain road curve based on a panoramic camera technology, which is suitable for the occasion of vehicle meeting warning on a curve on a mountain road. Background technique [0002] With the rapid development of my country's economy, the improvement of road infrastructure, coupled with my country's vast territory, complex and diverse terrain, and numerous mountain roads, there are many bends in my country's road traffic system, especially the U-shaped mountain roads that have blind spots for driving vision. The uphill and downhill curves are the most dangerous, and they are high-incidence areas of traffic accidents. Therefore, early warning of passing vehicles in blind spots on road curves has become an important means to reduce the probability of traffic accidents. [0003] At pr...

AI Technical Summary

Problems solved by technology

[0004] With the development of vehicle detection and road traffic safety technology, there are more and more auxiliary equipment used for vehicle driving safety. The current warning measures for driving safety on curves mainly include: (1) erecting a convex mirror at the curve to display the oncoming vehicle However, the distance of the convex mirror is limited, and it can only be displayed when the vehicle is very close to the convex mirror, and the warning prompt is not obvious, and when driving at night, the reflected light of the convex mirror may dazzle the oncoming driver. The reflection effect of the mirror is easily affected by bad weather such as snow and fog

(2) The vehicle-mounted anti-collision safety warning system based on radar, the system has a very good early warning effect for vehicles driving on straight roads, but the anti-collision early warning effect for vehicles at curves, especially those with blind spots blocked by mountains, is very limited , because the radar can only scan a certain straight line area in front, so the effective distance that can be scanned at the curve is very short

(3) A warning device for vehicles on curves based on geomagnetic sensors or laser sensors. Although this system can give good early warning to oncoming vehicles on the curve and is less affected by environmental factors, when there are vehicles staying in the curve or In the event of a car accident, the vehicles on both sides of the curve cannot give an early warning

Some scholars have proposed that based on the vehicle-to-vehicle communication technology of the Internet of Vehicles, the vehicles on both sides of the curve can communicate in time to achieve the purpose of mutual warning, but this method will undoubtedly increase the cost of the vehicle, and the current technology is not yet mature, so this either way
