Embodiment 1

[0030] This embodiment provides a system for quickly confirming the cause of abnormal parking at signal light control intersections, such as figure 1 As shown, it includes a video monitoring unit 1 and a green light state input unit 2 . The green light state input unit 2 outputs a green light state signal when the current signal light is green. The video monitoring unit 1 includes a video tracking module 11 , a state judgment module 12 , a data processing module 13 , an alarm module 14 and an image acquisition module 15 . The video tracking module 11 continuously tracks each vehicle entering its video tracking range. The state judging module 12 is configured to obtain the driving state of each vehicle within the video tracking range, and the driving state includes a stopped state and a traveling state. The data processing module 13 receives the green light state signal output by the green light state input unit 2 and the driving state of each vehicle output by the state judg...

Embodiment 2

[0038] This embodiment provides a method for quickly confirming the cause of abnormal parking at a signal light control intersection, such as figure 2 shown, including the following steps:

[0039] S1: Continuously track each vehicle that enters the video tracking range, and obtain whether the driving state of each vehicle is in a stopped state or in a moving state;

[0040] S2: Determine whether the signal light at the intersection is green, if yes, enter step S3, otherwise return to step S1;

[0041] S3: Determine whether there is a vehicle in the stopped state within the video tracking range; if so, enter step S4, otherwise return to step S1;

[0042] S4: Judging whether the vehicle immediately in front of the stopped vehicle is in a stopped state; if so, return to step S1, otherwise enter step S5;

[0043] S5: Send an alarm message to the monitoring center, prompting that the vehicle is abnormally parked; at the same time, collect the image information of the current in...

Abstract

The invention discloses a system and method for quickly confirming reasons for abnormal parking at a signal lamp control intersection to monitor whether vehicles entering the area of the signal lamp control intersection are parked abnormally in real time. According to the system and method, whether a vehicle is still motionless is judged immediately when a green light is on, whether a vehicle right in front of the vehicle is motionless too is judged immediately if yes, and it is confirmed that the vehicle is parked abnormally if no motionless vehicle exists right in front of the vehicle; to acquire the reasons for abnormal parking, intersection image information including the image of the abnormally parked vehicle is collected and sent to a monitoring center while alarm information is sent to the monitoring center; the monitoring center can learn the reasons for abnormal parking after receiving the image information according to recorded contents in the image information, and then corresponding measures can be taken in time. By the adoption of the scheme, it can be found out no matter which positions of the signal lamp control intersection a vehicle is parked abnormally, and the abnormal parking reasons can be acquired within several seconds.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a system and method for quickly confirming the cause of abnormal parking at an intersection controlled by signal lights. Background technique [0002] With the development of the economy, the number of motor vehicles has increased sharply. In order to standardize the traffic sequence of intersection signal lights, prevent and reduce traffic accidents, and improve the efficiency of intersection traffic, signal lights are installed at intersections with large traffic flow or frequent traffic accidents. Regulate the traffic order of motor vehicles at intersections. When unexpected events such as traffic accidents, vehicle breakdowns, traffic violations, rainy and snowy weather lead to abnormal parking at intersections, if not handled in time, it will quickly spread to the surrounding areas, and even lead to local road network traffic paralysis in severe cases. Ho...
