Embodiment 1

[0070] This embodiment will introduce the specific process of the traffic accident early warning method provided by the embodiment of the present application from the background recognition system side.

[0071] See figure 2 , which is a schematic flow chart of a traffic accident early warning method provided in the embodiment of the present application, the method may specifically include:

[0072] Step S201, acquiring a road condition image of a road section to be monitored.

[0073] It should be noted that the road sections to be monitored above can be accident-prone road sections determined according to historical experience, which can be determined manually, or can be determined by the system through statistics of historical traffic accident locations; or can be some road sections that need special monitoring, For example, a road section with a large traffic flow, a crossroad, etc.; of course, the road section to be monitored may also be any road section, which is not l...

Embodiment 2

[0090] See image 3 , which is another schematic flowchart of a traffic accident early warning method provided in the embodiment of the present application, the method may include the following steps:

[0091] Step S301, acquiring road condition images collected in real time by an image acquisition device installed on a road section to be monitored.

[0092] Step S302, extracting vehicle characteristic information in the road condition image;

[0093] Wherein, the vehicle characteristic information may include but not limited to vehicle outline information, license plate characteristic information, vehicle body color information, and vehicle lane information.

[0094] Step S303, identifying the same target vehicle in all road condition images according to the vehicle feature information.

[0095] Step S304 , according to the position difference of the same target vehicle in the road condition images corresponding to two different target time points, calculate a preset number...

Embodiment 3

[0105] See Figure 4 , is an interactive schematic diagram of a traffic accident early warning method provided in the embodiment of the present application, and its execution body includes an image acquisition device, a background recognition system and a display device. The interaction diagram includes the following steps:

[0106] Step S401, the image acquisition device transmits the real-time acquired road condition image of the road section to be monitored to the background recognition system.

[0107] Step S402 , the background recognition system calculates a preset number of speed values ​​of each target vehicle in the selected target road condition image within a preset time period based on the position difference of the same vehicle in the two road condition images at two time points.

[0108] Step S403 , if the background recognition system judges that the speeds of all target vehicles show a decreasing trend and finally decrease to zero, and the stoppage time of the...

Abstract

The embodiment of the present application is applicable to the technical field of road traffic and discloses a traffic accident early warning method and device, a terminal device and a storage medium,wherein the method comprises the following steps: acquiring a road condition image of a to-be-monitored road section; calculating speed values in a preset number of each target vehicle in a selectedroad condition image within a preset time period; if the speed of the target vehicle is in a descending trend and finally reduces to zero and the operation stop time of the target vehicle is greater than a preset time threshold, an early warning operation is executed. The embodiment of the present application actively predicts whether a traffic accident occurs and performs early warning, and doesnot rely on human alarm, thereby improving the accident handling efficiency and handling the traffic accident timely and effectively.

Description

technical field [0001] The present application belongs to the technical field of road traffic, and in particular relates to a traffic accident early warning method, device, terminal equipment and computer-readable storage medium. Background technique [0002] With the development and progress of society, there are more and more cars. The increase in vehicles will definitely bring great traffic pressure to road traffic, which in turn will increase traffic accidents. [0003] At present, when a traffic accident occurs, the traffic parties usually call the police, or passers-by call the police, and then the traffic police rush to the scene of the accident to handle the accident according to the relevant information provided by the police. However, this method relies on the parties concerned or passers-by to call the police. The traffic police rush to the scene to deal with the accident after receiving the report, which is very lagging, and it is necessary to communicate the acc...
