Problems solved by technology

[0004] With the development of science and technology, traffic pedestrian signs have greatly improved the original traditional technical means. One is to use infrared technology to install a pair of infrared anti-radiation alarm devices on both sides of the fork. When pedestrians or vehicles block When the infrared ray is emitted by the alarm device, the alarm device will alarm, prompting the cars on the main road to slow down, but the false alarm rate of the above-mentioned infrared alarm device is very high, as long as the moving target passes through the infrared ray to form a block, the alarm device will alarm
[0005] Another alarm method is to use the coil sensor. When the vehicle passes the coil sensor, the alarm device will alarm to remind the car on the main road to slow down when passing the intersection. However, the coil sensor alarm device needs to be broken when it is installed. Construction is carried out on the road surface, and it is buried underground. Since the coil is eroded by rainwater for a long time and repeatedly rolled by the weight of the passing cars, the line ages quickly and the sensitivity decreases, resulting in a large number of missed inspections and false reports.

Embodiment Construction

[0043] Product installation input:

[0044] (1) Set the area of ​​interest according to the scene, which is generally a polygon, such as a quadrilateral, a pentagon, etc., which usually have more than three sides. Currently, the number of polygons can be limited to one.

[0045] (2) Trigger alarm rules and related parameters: stay time in the area of ​​interest, target types such as: pedestrians, vehicles, travel direction restrictions of moving targets, etc.

[0046] (3) Algorithm parameters set according to scene conditions and user needs.

[0047] (4) Calibration information: reflects the relationship between the actual physical measurement value of the size of the moving target object and the measurement value of the image pixel lattice area, for example, the physical measurement value of the actual size of an ordinary pedestrian and each measurement value in the image captured by the camera The corresponding relationship of the measured value of the pixel lattice corresp...

Abstract

The invention relates to a method and a device for automatically warning road traffic safety, wherein the method comprises gathering video image data which is input by a camera, utilizing scene image which is gathered to build a background model, cutting out foreground image according to the background model which is established, comparing a foreground image model which is cut out with the character of a pedestrian or a vehicle in a preassigned bound, and judging whether the moving target is a pedestrian or a vehicle, if no moving target object is judged out near the crossing point of a side road and a main road, or the moving target is not a pedestrian or a vehicle, the device sends out normal signals, if a moving target near the crossing point of the side road and the main road is judged out to be a pedestrian or a vehicle, and then, the device sends out warning signals, warning a pedestrian or a vehicle to decelerate to run and carefully pass through.

Description

technical field [0001] The invention relates to a road traffic safety automatic warning method and device. Background technique [0002] With the continuous development of the country's economy, the per capita income continues to increase, and more and more people own cars. Cars bring convenience to people but also bring pain. According to statistics, the number of deaths due to car accidents is constantly increasing every year. How to build a safe and harmonious traffic road environment has become the focus of attention of the whole society. [0003] The vertical junction between the main traffic road and the branch road is an accident-prone area. Generally, a traffic pedestrian signboard is set at the junction to remind the cars driving on the main road to slow down when passing the cross section, so as to prevent pedestrians or vehicles from suddenly appearing from the branch road, causing traffic accidents. [0004] With the development of science and technology, traffi...
