Road safety monitoring early-warning devices and method

Abstract

The invention discloses a road safety monitoring early-warning method. A first shooting device and a second shooting device which shoot images in two opposite directions of a road are provided, the two shooting devices respectively send collected image information to a processor; and when a car frame occurs in images of one shooting device, the processor judges whether moving objects exist in the present image of the other shooting device, if yes, the processor emits a control signal for lighting a warning lamp. According to the invention, the two shooting devices shoot images in two opposite directions of the road so as to monitor the conditions of driving vehicles or moving objects in the two opposite directions of the road, image processing is combined with the warning lamp so as to carry out warning for meeting between two vehicles or between the vehicle and the moving object, traffic accidents are prevented, and the road safety monitoring early-warning devices and method are especially applicable to curves or crossings poor in view field.

Description

technical field [0001] The invention belongs to the technical field of road safety monitoring and early warning, and in particular relates to a road safety monitoring and early warning device and method. Background technique [0002] With the development of security monitoring, cameras are installed in road areas where traffic accidents are prone to occur, and the driving conditions of vehicles in this area are monitored and recorded, which provides strong evidence for the judgment of traffic accidents. When the vehicle travels to a curve or intersection, due to poor vision, it is impossible to distinguish whether there is a vehicle coming from the opposite direction or an elderly child playing in the curve or intersection. Or install a warning light that has been flashing to warn the vehicle that there are vehicles coming from the opposite side or old people and children playing, etc. at curves or crossings. [0003] see figure 1 , the road safety early warning equipment ...

AI Technical Summary

Problems solved by technology

The road safety early warning device has a simple structure and can reduce the occurrence of accidents to a certain extent. However, when a vehicle or pedestrian walks into the intersection from the hollow position between the infrared emitter and the intersection, the infrared emitter cannot detect the passing of the vehicle or pedestrian. The warning light cannot be triggered to light up, and there is a risk of traffic accidents

In addition, the device cannot record video in time, which is not conducive to investigation and evidence collection after an accident

This road safety early warning device is generally used in residential areas with relatively slow speeds. For fast roads, the infrared transmitter may not be able to detect fast vehicles, and cannot provide effective safety warnings for passing vehicles.
