Embodiment 1

[0031] Figure 4 A flowchart showing a method for obtaining evidence of vehicle traffic violations according to an embodiment of the present invention, as shown in Figure 4 As shown, the method includes the following steps:

[0032] S101: When the head of a vehicle arrives at a predetermined area behind the stop line, the front camera takes a first photo, and at the same time sends a first co-shooting instruction to the rear camera.

[0033] S102: The rear camera takes a second photo according to the first co-shooting instruction.

[0034] The co-shooting command here is the co-shooting command. After the front camera takes the first photo from the front direction, the rear camera also takes the second photo from the rear direction simultaneously.

[0035] Since the second photo is taken from the direction of the rear of the vehicle, for a small car with a shorter body (such as less than 6 meters), the rear license plate number must be reflected in the second photo; but wh...

Embodiment 2

[0049] Figure 5 A flow chart showing another method for obtaining evidence of vehicle traffic violations according to an embodiment of the present invention, as shown in Figure 5 As shown, the method includes the following steps:

[0050] S201: Determine whether the traffic signal light corresponding to the lane where the vehicle is located is a red light. When the traffic signal light corresponding to the lane where the vehicle is located is red, perform step S202; otherwise, perform other operations or no operation.

[0051] This step can be carried out by the rear camera. For example, the rear camera judges whether the traffic signal corresponding to the lane where the vehicle is located is a red light according to the color of the image corresponding to the traffic light in the video picture taken by the rear camera; it can also be done in other ways. Executing, for example, judging whether the traffic signal corresponding to the lane where the vehicle is located is a ...

Embodiment 3

[0072] Figure 6 A flowchart showing another method for obtaining evidence of vehicle traffic violations according to an embodiment of the present invention, as shown in Figure 6 As shown, the method includes the following steps:

[0073] S301: When the head of a vehicle reaches a predetermined area behind the stop line, the head camera takes a first photo.

[0074] S302: The head camera associates the first photo with the first identifier.

[0075] S303: The head camera recognizes the first license plate number of the vehicle according to the first photo.

[0076] S304: The front camera sends a first co-shooting command to the rear camera, and the first co-shooting command carries a first logo, a first photo and a first license plate number.

[0077] For example, the first identification is ID1, the head camera associates the first photo with ID1 (for example, the first photo can be named ID1), and the license plate number is recognized as ABCDEFG (ABCDEFG refers to the f...

Abstract

The invention discloses a method and a system of obtaining evidences of vehicle traffic violation. The method comprises the steps of, when the head of a vehicle reaches to a preset region behind a stop line, taking a first photo by a head-end camera and sending a first shooting assistance instruction to a tail-end camera; taking a second photo based on the first shooting assistance instruction bythe tail-end camera; when the driving track of the vehicle is intersected with the stop line and / or the current lane driving rule line, taking a third photo by the tail-end camera and sending a secondshooting assistance instruction to the head-end camera; taking a fourth photo based on the second shooting assistance instruction by the head-end camera; taking a fifth photo by the tail-end camera when the vehicle carries on driving forwards; synthesizing the third photo and the fifth photo to serve as a first evidence, synthesizing the third photo and the fourth photo to serve as a second evidence, and synthesizing the third photo and the fifth photo to serve as a third evidence. Through cooperative shooting of the head-end camera and the tail-end camera, the number of the obtained photos is relatively small, and the requirements for data processing of an information processing device are relatively low.

Description

technical field [0001] The invention relates to the technical field of intelligent transportation, in particular to a method and system for obtaining evidence of vehicle traffic violations. Background technique [0002] At a traffic intersection, running a red light and violating the driving rules are all traffic violations. The existing methods for obtaining evidence of vehicle traffic violations have been able to better obtain evidence of traffic violations for small vehicles at traffic intersections; however, for large vehicles, reliable evidence of traffic violations cannot be obtained. [0003] Taking a vehicle running a red light as an example, citing the requirements of 4.3.1.1 in the public safety industry standard GA / T 496-2014 "General Technical Conditions for Automatic Recording System for Running a Red Light", the system should be able to record at least the following 3 photos reflecting the process of running a red light Picture: (a) A picture that can reflect ...
