Traffic accident scene safety protection and monitoring method and device

Abstract

The present invention discloses a traffic accident scene safety protection and monitoring method and device. The method comprises the steps of: employing a camera to collect road surface images of a traffic accident scene, and determining a limit of the prohibited area according to the position information and the shooting direction of the camera and the road surface images; and employing a radarto monitor whether there is a vehicle entering the limit of the prohibited area or not, and if it is monitored that there is a vehicle entering the limit of the prohibited area, performing alarm processing. The traffic accident scene safety protection and monitoring method and device achieve construction of an accident lane prevention area boundary with clear boundaries in logic so that the traffic accident scene protection early warning response efficiency is improved, dangers when the people's police perform reconnaissance and cone barrels are arranged at the accident scene are effectively avoided, influences of weather factors on a current safety protection mechanism are avoided, injuries and deaths of the people's police and the masses caused by secondary accidents are avoided.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method and device for monitoring traffic accident scene safety protection. Background technique [0002] When dealing with traffic accidents, traffic police should not only properly handle the accident and treat the wounded, but also set up restricted areas at the scene of the traffic accident through safety protection measures to prevent motor vehicles from entering the scene of the traffic accident, and prevent the police and the public from being affected by secondary accidents and causing casualties. . [0003] At present, the more common way to set a restricted area is to place a reflective cone loaded with sensors on the periphery of the traffic accident scene, and once the vehicle hits the reflective cone, an alarm will be issued. The advantages of this technology lie in its simple operation and strong practicability, but there are still the following problems: First,...

Problems solved by technology

The advantage of this technology lies in its simple operation and strong practicability, but there are still the following problems: First, it cannot solve the problem of early warning when the police place and recover the cone buckets at the scene of a traffic accident. Because there are no relevant warning signs on the road, the police are in the most dangerous state; second, the response efficiency of on-site protection and early warning is not high, and it takes a long time for the police to complete the deployment of on-site protection facilities such as cones, which greatly reduces the efficiency of establishing a protection system

After communicating with the grassroots police, it is generally reflected that the existing cone anti-intrusion alarm system is greatly affected by the natural wind or the wind and vibration generated by vehicles passing by in adjacent lanes, and it is easy to generate false alarms, which will have a certain impact on the police's on-site investigation and disposal.
