Embodiment 1

[0028] refer to figure 2 , a vehicle early warning system based on roadside double flashing light recognition of the present invention, comprising: an integrated monitoring device, an early warning display, an early warning broadcaster and a control center; The millimeter-wave radar and camera are integrated on the road, and the millimeter-wave radar is used to obtain the speed and position information of each vehicle on the road, and transmit it to the control center; the camera is used to obtain the road condition information on the road, and its transmission to the control center;

[0029] The control center is used to identify whether the vehicle has turned on the double flashing lights according to the obtained road condition information, vehicle speed and position information, and determine the danger level of the current road condition. Corresponding warning information;

[0030] The early warning displays are arranged equidistantly on the roadside of the road, and a...

Embodiment 2

[0034] refer to figure 1 , a vehicle early warning method based on roadside double flashing light recognition, comprising the following steps:

[0035] Step 1, obtain the road condition information on the expressway in real time, extract the image of each vehicle; obtain the speed of each vehicle;

[0036] Among them, the road condition information and the speed of each vehicle are obtained through cameras and millimeter-wave radars set at intervals on the roadside of the expressway;

[0037] Step 2, using image grayscale analysis to select the candidate area in the image of each vehicle; using the maximum inter-class variance method to segment the candidate area, and then undergoing morphological transformation to obtain the candidate headlight area;

[0038] Specifically follow the steps below:

[0039] (2.1) Use the HSV color space to perform threshold filtering to obtain the corresponding candidate vehicle taillight area binary map;

[0040] Wherein, the threshold value...

Abstract

The invention discloses a vehicle early warning system and method based on roadside double flashing light identification. The system includes: an integrated monitoring device, an early warning display, an early warning broadcaster and a control center; the integrated monitoring devices are arranged at intervals on the side of the road , which is integrated with millimeter-wave radar and camera, millimeter-wave radar is used to obtain the speed and position information of each vehicle on the road, and transmit it to the control center; the camera is used to obtain road condition information on the road, and transmit it To the control center; the present invention can detect in time the vehicle that brakes and decelerates and turns on the double flashing lights due to an emergency accident on the road, and warns the rear vehicle through the roadside LED information board and voice broadcast device to avoid the rear driver A series of rear-end collisions is caused by the lack of timely braking response due to the blocking of the line of sight or distraction of the vehicle in front.

Description

technical field [0001] The invention belongs to the technical field of traffic safety, and in particular relates to a vehicle early warning system and method based on identification of roadside double flashing lights. Background technique [0002] Affected by factors such as the size of the vehicle in front or his own distraction, it is difficult for the driver to detect the emergency braking of the vehicle in front in time during driving, and his own vehicle fails to brake in time, resulting in a rear-end collision accident, and more seriously, it will cause the rear vehicle Large-scale serial rear-end collision accidents are produced because of the same situation. Therefore, if the sensor can be used to identify the location of the dangerous situation in time and give early warning to the vehicles behind in time, the occurrence of such accidents will be effectively avoided. Contents of the invention [0003] In order to solve the above problems, the purpose of the prese...
